DynCache recommended settings for Windows Server 2008R2 ?

Hi All,

We are facing issue where Windows 2008R2 file server with all latest updates with 24 GB RAM is giving us low free RAM alerts. The server earlier had 16 GB which has been recently increased to 24 GB and still we are facing the issue. When checked through RAMMAP, we found that Active memory utilization for server stays around 17 GB while Standby memory stays around 1.7 GB. RAM utilization drops below 10% once "Empty System Working Set" is used from RAMMAP utility.

As per different discussions here on Technet forums, the solution I found is to install DynCache service (https://www.microsoft.com/en-us/download/details.aspx?id=9258). Now I have searched on Internet but I am not able to find any recommendation regarding the values to be input for below parameters:

"BackOffMBytesOnLowMemory"
"MaxSystemCacheMBytes"
"SampleIntervalSecs"
"CacheUpdateThresholdMBytes"

Can someone please tell me what parameters are safe to use ? Are there any other parameter which I forgot to mention but needs to be modified as well ? Please share any guidelines/recommendation provided by Microsoft regarding same.

Regards,

Praggwv

MS access 2007 DB crashes running query on Windows 2008r2 Error event reports MSVCR80.dll as cause

HI all, not sure where I should be posting this question as I am not sure if it is a Window s2008r2 server error or Office 2007 / Access 2007 problem.

 

Every 4th or more time we run a query on our Database MS Access 2007 version that we have split between backend and front end.

It crashes, originally message it gave me was unable to write to memory, but now it says the following as per event log below Windows 20082r

We are running Win 2008r2 on a virtual drive.

I have reinstall office 2007 and it hasn’t made a difference.

Ran Scan SFC Nothing.

 

Happens no matter who logs into our server.

What is interesting, although I suspect down to different version of Office and Operating system, doesn’t happen if a client PC runs the Database query.

 

The more I search and read forum son this, the more confused I get, as I know from experience with MS flight sim, that a similar thing happens, and some hotfix or software someone put on fligthsim.com fixes that problem,. But this is not as easy.

 

Hopefully someone has some more suggestions I can try.

Thanks

Phil

Windows 2008R2 SP1 on UEFI 4TB drive inconsistent boot process

November 17, 2016, 10:01 am

Hello everyone,

Server is Dell PowerEdge R720 running Windows 2008 R2 with in RAID 10 array, single C partition.  What happens is and it is very inconsistent, that after restarting, we get the notification that there is No operating system. 

This started happening after installing Veeam Endpoint backup.  Talked to Veeam support in length and they do not seem to think it is on their end. Uninstalling Veeam appears to eliminate the issue.

With Veeam installed, to get past the No operating system after restart, I boot with the Veeam recovery USB and select startup repair. Startup repair fails with the error that there is no OS, but after I exit the utility and restart, the server starts up normally. I can shutdown and restart the server multiple times in a row with no issues.

Any suggestions are appreciated.

DNS in 2003 AD

I have a Windows 2003 AD. I have introduced Windows 2008 Servers to the domain. I use Hyper-V on 2008 and one of the servers virtualized is a Windows 2000 Server that has a web App running. It has been working fine and is accessed by windows 7 pro 64 and 32 bit.

Lately, some of the workstations can not access the site on the virtualized windows 200 server.  I can easily fix that by running the command  ipconfig/renew, refresh he browser and they are in.  I can also restart the windows 7 workstation and they can then access the site.  Any direction or thought on what could be causing this would be greatly appreciated.

Windows 2008 R2 server backup behavior after volume resizing

I seem to recall (from a previous painful episode) that if you are backing up Windows Server 2008 with Server Backup; and you change the physical properties of a volume on a hard disk (change the size) then Server Backup resets - it wipes the old backup database and starts again. I want to do this again (change the size of two of the volumes) so if I remove the current backup disk using the wizard; then add a new one; will I still be able to access all the files from the old drive from within the program? Thanks for your time -it's much appreciated.

32 Bit and 64 Bit error on Windows 2008 R2

I have Exchange 2010 running on Win 2008 R2 Server, 64Bit.

 I cannot open command prompt, dns, dxdiag, IIS etc. The following error appears every time:-

  "The version of this file is not compatible with the version of windows you are running. Check your

    computer's system information to see whether you need an x86 (32 bit) or x64 (64 Bit) version of the             program and then contact the software publisher."

I have uninstalled some windows update, rebooted the server, initialized chckdsk but no change.

Some exchange 2010 tools from the TOOLBOX are not functioning as well, namely queue viewer and mail flow troubleshooter, even though a different error is displayed, i believe its something to do with the OS.

Kindly advice

Clipboard Redirection Group Policy

I'm trying to disable the use of clipboard redirection for all but a few users.  Enabling the "Do not allow clipboard redirection" works as far as disabling for all users, but I cannot seem to create the exceptions to allow those few users to continue being able to use RDP clipboard.  I've denied the GPO from applying to those specific users and their PCs (it's a computer config setting) but even after gpupdate it still doesn't allow those users to use the clipboard even though I can see the policy was filtered out.

Any assistance creating the exclusions would be greatly appreciated.  Thanks in advance.

Trust relationship between WS 2012R2 and WS 2016 TP5

Hi, we're trying to create a trust relationship between this two servers, but a lot of errors popped up.

"The server is not a valid zone Domain controller"

"Acces Denied"

"This process can't be performed in this domain"

We're running the OS in spanish so the translations might not be very acurate.

So my question is, should we use the final release of WS2016 ? Or there's something we can do to make it work?

Regards!

Server 2008 R2 problems with KB3185330 October 2016 Security Monthly Quality Rollup

November 18, 2016, 9:08 am

Hi there,

could need some help with windows updates... :-)

I am on 2008R2. During the last month we installed the KB3185330 october rollup update and it failed. Due to this problem we were not able to install the KB3197868 november 2016 rollup.

When reverting/removing all "uninstallable" updates which where done since then, the KB3185330 did not reoccur in the list of available updates. After reapplying all available updates, KB3197868 november 2016 rollup worked fine.

We discovered there were several security fixes, which are included in the KB3185330 from october. The system is now missing these patches.

If I manually download KB3185330 and try to install it says: "update is not applicable to your computer"

Clearing the windows-update history/cache/data dirs etc. did not help.

BUT: Restoring a machine from a pre-KB3185330 backup, pulled ALL updates. Including KB3185330 and everything worked on update-installation. It is also listed in the installed updates.

Well restoring a complete environment with several servers to a backup-state from 1-2 months ago is clearly not what I want to do. But this shows its working in general.

I know there is a lot discussion on the web on that update, but mostly it seems non-professional or unapplicable to me...

Any ideas how i could re-enable KB3185330 for the machines?

Best Regards

Windows Server Essentials 2016: WseMgmtSvc and associated WSE services don't start on reboot of server

November 18, 2016, 7:16 pm

   I thought that I had successfully negotiated the replacement of a 2012 R2 OS with the new 2016 OS, but then I found out that after a reboot, I could not remotely log into the server.  On closer inspection, I found that that the WSE dashboard was not populated with any of the device or user or storage data that had been so carefully supplied during the initialization of the server.  A little research suggested that the Windows Server Essentials Management Service was not running, which was in fact true, and I used the Server Manager to find and start the service.  But I also noticed that there were other WSE services that had not been started.  The absence of these services has a disastrous effect on the server, since it will not perform backups or share files or allow remote access until these services are activated.  In essence, the server is useless until these services are started, and after they are started, the server resumes all it's tasks very nicely.  

     So the only solution I have discovered is to sit in front of the server console, login, and use the Server Manager to start the services.  But I fear that this problem will require this on-site intervention frequently, since I presume the server will update itself and reboot overnight.  This is not a good solution for me, because I do as much remote administration as I can.  I would like, of course, to discover what is keeping the services from starting and correct that problem.  But failing that, at least I should be able to provide a script of some sort to run automatically at reboot to start these services without requiring personal intervention. 

     I have read that this phenomenon may be associated with the corruption of the file named DevicesInfo.xml, found in this folder: Program Data\Microsoft\Windows Server\Data.  During the process of configuring the server, I had several hard drives attached in several different combinations, and perhaps this xml file became confused in the process and is indeed corrupt.  But I have not found a way to re-create it. There is some discussion about this here:

https://social.technet.microsoft.com/Forums/office/en-US/e2bbc4c5-d26c-4179-8f28-9aff28cababc/devicesinfoxml?forum=winserveressentials

but according to the referenced post, the issue has not been resolved. 

  I have found that this forum can help supply good answers, but sometimes it takes quite a while for them to emerge.  As always, I will appreciate any and all suggestions and information relevant to this issue.  Thanks!

Strangest WMI problem I've ever seen. Reverse DNS related

November 18, 2016, 1:00 pm
$

This is incredibly odd.

We have a site (HQ) and several remote sites around the world.  WMI queries work perfectly well to all the remote sites except one.

We either get the classic "RPC unvailable" error or the "Call was canceled by the message filter" one.  This happens whether we query with the IP address, NETBIOS name or FQDN.

The ONLY thing that fixes it is to delete the perfectly valid PTR records for the query target and flush the dns cache.  Then, WMI queries to the IP address and hostname works perfectly.  Well, until the PTR record gets re-created.

I know that WMI can have issues if the PTR and A records don't match up but that is not the case here.  The PTR records are perfectly fine.  In fact, we've configured DHCP to register them on behalf of the client!

I'm befuzzled....
