Just curious - what's the system time/date on that workstation?

I ask this because if the date is wrong on the system, it will be wrong in SO-A as well.
 
If the system is not maintaining the proper time then you probably need to replace the CMOS battery on the mother board, reflash your BIOS and maybe consider setting up time synchronization on your network (although the last step is not necessary).

Here's a neat little program I use to keep all the workstations synced up.

This program acts as a client and server.  You can set it up on a machine that has internet access, and let it serve the local net.  

There is NOTHING in my experience that would pull a date different than the system date for one functional component of a client server software system. Then again, I have seen all kinds of things that are downright WEIRD happen in my years in this business. What is really neat is Lynn has seen even more!
 
Oh and Laura, if it is the CMOS battery causing a problem, Windozzzze will give you a warning at startup and you would need to press a function key (I think it is F1) to continue starting with a faulty CMOS battery.
 
Anyway, Tim, why use a separate program when you can synchronize the server with any of the major time servers out there and then use the /nettime command to keep workstations synched?

Ooops..... Meant to type Kevin. Sorry Tim.

You could manually set and periodically check the time on the server and then set the workstations to synch to that time.  That way at least you would have a consistent time across the network.
