Hi Vimal,
Have you change the parameters of hostname in the profile files? (X:\usr\sap\SID\SYS\profile) it seems you are using the same SAPSERVICESID user, you need to recreate OPS$ users
Please check note: Note 50088 - Creating OPS$ users on Windows NT/Oracle
By the way... how did you change the default password?
Hope it helps!
Cheers
