I am new to networks as well as servers
In my organisation I have 4 servers all running win server 2003 enterprise sp2. The problem is that they were working fine for almost a year and suddenly their sharing options disappeared and the server hangs up after some time.
The issue is temporarily resolved after restarting the server but recurs periodically.
I have Kaspersky v6 installed on them. There is no Active Directory nor domain. They are all on a workgroup. I also have an Astaro 320 security gateway.
What could be causing this to occur and how do I fix it?
