Hi Mohammed,

Ther are several things here to check:

1- What particular time the servers gets hunged?

2- How the switches are connected? Do they have single link or they have any etherchannel configured?

3- Whats the link utilization and cpu utlization during the issue? And also the status of Servers?

4- Were is the file server located?

HTH
