Acronis 11.5 on Windows 2003 Server and VSS Conflicting Causing Crash

I have a Windows 2003 Server using Acronis 11.5 backup & recovery software.  The problem I'm having is before the backup can complete the server becomes unresponsive to the network.   This problem seems well documented throughout the net.  I want to disable VSS completely as I feel this will solve my issues.  My question is, is this a good idea?  The problem isn't constant but a couple times a week.  Thanks in advance.

If you disable VSS completely then you will not be able to backup the system online. Means thag backup will be possible from boot cd only.
Have you tried it witout antivirus?

Doesn't look like this patch is applied per my add remove programs.

Also disabling the virus protection didn't seem to work.  Server ran OK for a few days then back to normal unresponsiveness.

Do I understand it properly - the only thing affected is network, right?
Does all the rest function properly?
And where do you image the server? Network or local drive?

The workstations used to receive DHCP and DNS info from the server.  Since these issues started I moved this functionality to the router.

The server becomes unresponsive.  Meaning that the power button must be held down in order to recover.  Unfortunately I'm never present when the halt occurs to I can't get exact details on what if anything is happening on the monitor attached to the server.

Images are saved to a USB attached HD directly attached to the server.

So the dns ip is no longer the file server?

This sounds like a memory leak.
How much ram,what services do you have running on it and have you run a best practices analyzer on it?

Ok this is more precise information.
When it hangs and you do hard reset - anything suspicious in Event Log viewer?
Acronis installs its own VSS requestor so it could ne conflicting with native MS requestor. Just thinking loud. But if the hanging occurs at the end of the backup process I would suspect some partition which could be a culprit.
Can you take a screen shot of Windows Disk Management and post it here?

C: and D: are on a RAID1 array containing 3 disk.  The others are single connected USB drives where server and workstation backups are stored.  Best I can tell I haven't had any restarts since July 27th.  The only change I can remember making is selecting do not use VSS to create snapshot.

Please run vssadmin list writers command.
See its output. Are all writers working OK?
Then, try to take backup of the system using Windows Backup feature. It uses VSS as well. You will see if it hangs or not.
As you say it works when VSS is disabled and the fact that it does not restart means that Acronis is using its native hot processing driver for this. Which is ok but not so good as VSS. Especially when you have Exchange running on this server.
The standard hot processing driver from third provider such as Acronis will take backup of data as is.
If you use VSS the requester will tell to server applications - stop all iterations, you are going to be imaged. Thus it guarantees data consistency.

Can you enable VSS and try to take backup using Windows backup feature? There is NT backup in 2003 yet available. Thus you can localize the problem and narrow it either to Acronis or to VSS.

I can try but since its been stable since disabled I'm not sure I want to.  Is there any danger in leaving it as is?

No danger. Normally the danger would be if you run there Exchange server. But as long as you don't it is ok.

VSS backups up locked files and I'm not real sure that without it you are getting a complete backup.

That's the problem.
If your AD is locked or if somebody has a word or excel spread sheet open or another db type file,that file does not get backed up,it gets skipped..
VSS was a technology that allowed for a snapshot of an open file that M$ came up with so that 3rd parties didn't have to write their own.

And with an image based restore product ,I would be nervous about the consequences.

In Acronis two technologies are used. It does not ignore files. They invented VSS like driver for online backup of the system and then made Acronis VSS requestor for correct applictaions backup. The difference is that standard backup is not aware of server applications and VSS is aware amd makes the databases stop.
The only problem you could have is that changea done between start of backup and its end will not be saved in backup. In case of VSS these changes are either saved in temp files such as lgs in exchange or no changes are allowed by service itself.

Backups happen daily at 12:00am when no one is accessing the network.

Went about two weeks with no restarts.  This thing is aging and will be replaced soon.  Unfortunately just going to live with it until its replaced.  Should happen within the next couple weeks.  Thanks for your efforts.
