Try the bcdedit /set {default} USEPLATFORMCLOCK on trick (reboot required). Also, what network adapter you have in server 2?

Thank you for the comments.

After monitoring the server using 'perfmon' I got to know that the disk read/write speed seen bit slow. I got these 5 sectors as bad.

Perfmon result:

Server (C:)\%disk (C:)\Avg. Disk (0 C: X: Y: Z:)\Avg. (0 C: X: Y: Z:)\Avg. (0 C: X: Y: Z:)\Avg. Read time sec/Write Disk Read Q Length Disk sec/Transfer Disk sec/Write

 

Server 1 7.136396 0.5939E-3 0.07135 0.60109E-3 0.593206E-3

Server 2 8.3509 7.1190E-3 0.08348 6.82229E-3 6.15297E-3

My OS is installed in disc C. By looking in to these I can tell that OS may become slow by the slow response of read/write operation in C but in the result of loop test I don't understand that how the read/write operation in disk C effect the loop test. Is this because OS became slow by the read/write operation in disk C? Or is this due to something else? Please enlighten me...

Thank you for the reply JFFulcrum

bcdedit /set {default} USEPLATFORMCLOCK yes did not solve the problem instead the server got much slower than before so I rolled back. Is there any other way track the problem?
