I went form 2002.1  to the latest ISTECH update this morning.   Ever since I have done this my two XPpro stations shut off every 30 minutes or so.  They just automatically cut off at the exact same time.  Not just out of DBA but dead off.
 
My 98 & NT workstations are fine!
 
Is this a possible side effect of the upgrade?
It sounds like a VIRUS, but our DBA workstations/server are not connected to the internet.   I just hooked the internet to try to run an online scan,   but the workstations keep cutting off.
 
could be that I have a antique version of Pervasive and the upgrade iritated it?
 
Please...any and all ideas & suggestions appreciated.
 
Thank you.

My husband just said that since they are turning off at the exact time.  It must be related to the server.  
 
Weird thing...both XPpos have a backup.   so the problem is not electrical.
 
Gosh....has anybody had this happen?
 
 

I actually have to push the start button. This just started today, after the upgrade  
 
BUT (below) has been happening for a while.
Sometimes one of them slowly looses its connection to the server.   Its weird.    Our networked drive (where we all share documents) will slowly start loosing files.  At first only a few or so  of them are gone. *** KINDA LIKE THE PHOTOS IN BACK TO THE FUTURE*** Then after a while they are all gone.  But if you shutdown and comeback up, they are all there. (for a while)   Sometimes we get a message that we have lost the conection to the server.
 
I don't know if the two problems  are related.
 
Also when I mapped them I may have messed up.   They all have same domain name.
 
Thanks,
Laura
