Quickbooks crashes with multiple users, other network problems, please help!

Some databases do not like dropped connections, so that can cause all sorts of problems. The beeps are as you said likely the UPS's. Are the batteries working properly ? If not you may have equipment temporarily shutting down, such as the switch which should be plugged into the UPS. I would test the UPS under a load for starters. Also where you are having disk errors, back up that data NOW!
QuickBooks has a data verification tool you should run, located under file on the menu bar. This will tell you if there the file is corrupt and adding to your problem. If it does report errors you can do a data rebuild, but do a back up of the data first. It should ask you to do so, but just in case...
One other thing, make sure power management is turned off on all network adapters under the network adapter's properties in device manager.

Yes RobWill is correct you have to reconfigure the total client office infrasture /ups/server and network problems.So bffore doing this take the imp data backup on external USB hard disk and then check the UPS is properly running and batterries are charging and giving the backup or any reseting problem to UPS after power management factor solved then automatically system / server restart and HDD error  problems will be solved.

Then In network management check the router/ switches /Network cards /cat5 cbales problem using UTP tester and using network monitoring tools .If 10-20 pc's on the network then you can check the pc's congiguration one by one for antivirus scan and wiindows / antivrus / software updates .

And For Quickbooks application take the support from the vendors / enginners of QB application to take the backups/reinstalltion and restore of data.

Ok, fyi- data is all backedup.  Also, I'm getting Userenv 1091 event on the server:  group policy client-side extension Security failed to log rsop data...etc.

would this be a cause for network problems?

We have a brand new UPS on the way.  I'm just trying to figure out if this is a network hardware problem, or a server/AD problem.  I have some switches I can stick in, but I want to make sure I'm barking up the right tree.  I will look in to the other suggestions.

Also, I tried to verify QB data yesterday, and it would either freeze up, or make it partially, then stall.  I may try to install QB on the server, or move the data files, verify them, then move them back.

Yes, SBS is the only server for this business.

Good idea. Could get corruption if you do data re-build over your network.

What version of QB ? year and release # ?
Not 2004/2005 R4 by any chance.

1091 and 1704 are the ones showing up, 1704 is info, not error:  Security policy in the Group policy objects has been applied successfully.

Also, I was exploring file corruption as a cause.  Here is a QB thread for people with some similar problems(error code 64 sometimes shows up):  http://www.quickbooksgroups.com/webx/forums/install/Networking/405

I ruled out corruption, unless it happens instantly by copying a fresh sample business QB file over to the share.  I could open the file from the 1st computer, then all subsequent connections failed and locked up QB.  I'm now going to attempt to share the files from a workstation and see if the problem happens then.  Right now, it appears that the rest of the network is functioning fairly normally aside from the QB problem.  Once I have a workaround, I will focus my efforts on the server.

I'm going to do an in-line swap to a workstation as a temp server using sbsmigration.com, rebuild the server with new drives, and migrate it back online.  

QB works if it is shared from a workstation.  The rest of the network aps seem to be running somewhat normall now.  I actually think that QB from the server was crashing the other Aps, if that is possible?  Now I think with new UPS on the way, I think they are willing to let me overhaul the server situaton in one manner or another.

I had asked earlier about QB version as I ran into a similar situation a little less than 2 years ago, at a client site. As soon as they upgraded from release 3 to 4 ( I believe 2004), if there was more than 1 user using QB, the application would hang, actually appear to freeze, and lock up the entire workstation. It would, after 1-3 minutes, return to normal. This happed numerous times per hour. It too was on SBS 2003. When I looked into it on the QB forum, a few others had the same issue. QB said there was no problem. Before it was resolved they swtched to 2006.

I think they are on 2005.  They are switching to a different accounting system in a few months, so we probably don't need to upgrade...

Thanks for the info, it is possible that someone messed with user rights.  Maybe that is what fixed it when I moved them to a different share with rights to "everyone".  We didn't have QB installed on the server it was being shared off of, but we never had and it worked without incident.  Does the new QB user that it creats use up one of our per user CALs?

I should think not.  No more so than any of the other built-in accounts.

I accepted Manic's suggestion as the answer, however I am not able to verify what was causing the problem.  I have a new UPS to install, and I'm going to free up some time to rebuild their server.  I'm leaning more towards something like what Manic suggested because once I moved off the share and onto a share on a workstation, the QB and network crashes stopped.  

Thank you for all of your input, and I'll post back here if I find out anything else!
