unmatched RepositoryStamp issue in DAC

Sometime dac throws below error when accessing dac from command line.

ERROR:
com.siebel.etl.net.DACCommandLine main
INFO: Illegal message received, with unmatched RepositoryStamp! Ignoring it.

Here is what you can do to resolve this error
1- DAC server and client repository stamp are not in same. ( This happens when we move dac repository from different client ) .
2- Login to the client from where repository migration happened.
3- Check Help–> login Details- and copy Repository Stamp

change RepositoryStampVal=
5- Bounce the dac server.
