i am using windows 2000 server with db2ver 7.2 on two servers in my domain. i upgraded one to fix pack 10a and left the other at fixpack 7. i now cannot connect to the databases on the server using fixpack 7 using the connect to [database] user [username] command.

I have not heard about any problem with this fixpack. I asume that you performrd all the post-installation tasks after applying the fix packs and also that there is no change in the configuration.

Try rebinding and I think :

db2 CONNECT TO DB
db2 BIND c:\sqllib\bnd\db2ubind.lst BLOCKING ALL GRANT PUBLIC
db2 BIND c:\sqllib\nd\db2cli.lst BLOCKING ALL GRANT PUBLIC
db2 terminate


I hope there is no change in the DBM cfg (SVCENAME) and you can ping the box.
