Sudden outbreak of sharing violations, can't open/delete/save file

[Guest Rich]

Hey everybody. In the past couple weeks, maybe a month, we've had a sudden

outbreak of sharing violations, can't open/delete/save files, those types of

issues on 2 Win2K file servers. The one server, I've replaced the RAM and

NIC, also ran a full blown chkdsk on the volume that had issues, and still

having issues. Now that the other server is having issues i'm thinking that

maybe a recent MS or VirusScan update (the only 2 things similar on both

servers) may have caused this. Anyone else having issues like this recently,

or know what else I should be looking at to find out what's going on?
