Thanks for the prompt reply Paul. here is our server setup :
OS Name : windows server 2008 R2
System Model : VMware Virtual platform
Memory (RAM) :8.00 GB
Virtual Memory : 16.0 GB
Page file space : 8.00 GB
Also I checked with our infrastructure manager and it seems that the memory consumption goes high and not CPU. Also have some users in remote locations connected thru VPN (Cisco client), another important thing this issue was not there when we had only Finance department Live and after the full conversion (30 users) we started facing the disconnection issue.
