I got this resolved, thank you.
Hi Santosh. I'm sorry no one else was able to assist you with this. Would you mind posting your resolution for knowledge capture? Thank you.
Earlier I created a catalog and had not downloaded the patches. I ran PAJ and then was downloading missing patches, I think this was creating problems.
Also another thing was I changed the SMB password after the patches were downloaded.
So not sure regarding the behaviour.
I created a new Catalog and set the password, downloaded patches before runing PAJ and remediation it worked.
