Really Miserable Problem

[Gonzo40]

Dear all

its really nice to join your forum

i am facing a problem since 6 months, i am having windows server 2008 Domain controller that have shared folder , its Global catalog server , i am having another secondary domain controller ( windows server 2003) in another site connected to the G.C. server through VPN tunnel.

The problem takes care on Domain 2008 suddenly

1)i cannot access the shares (all users)

2)i cant rename some files on specified path on shared folder

 

the only solution is to restart the server , but now a days i had to restart the servers for 2 times to solve the problem

 

are their any suggestions
