Terminology questions:

You say the domain is on server 1, so that will mean that the Primary Domain Controller is server1. Is server2 a Backup Domain Controller? If yes, then all Domain Controllers will need the KiXtart RPC service.

Secondly, enable directory replication to replicate the logon script into all NETLOGON folders on all domain controllers.

Thirdly, use a LOGON.BAT file to call the KiXtart script and use a simple test script like
code:
if ingroup("globalgroup_name")
 ? 'is in group'
else
  ? 'is not in group'
endif
Also, check the KiXtart Starter's Guide in the FAQ section.
