Hi, I am trying to connect to Oracle thru SS2k. Oracle client is installed on the machine. tnsnames.ora file in \ora81\netowrk\admin directory has the entry for the oracle connectivity. I could do a tnsping from this machine, and also connect to SQL*PLUS. But, when I try to connect using enterprise manager/linked server, it freezes the system and I have to do a cold reboot. Any help greatly appreciated.
