This error is common for all the linked clones from different pools , the view agent version is  6.1.1 To check further I did below steps:

1. Reinstalled vmtools and agent on master image , recomposed - same error.

2. Logged in to one of the linked clones from vcenter to check the connectivity , successfully able to ping and resolve both connection servers , telnet to 4001 JMS also works fine.

3. Followed vmware kb article 2007319 , installed the MS hotfix - still the same problem.

4. checked VMD agent logs , couldn't see anything relevant.

Finally I tried to install a different version of view agent , I installed agent 5.3.0 and to my surprise it works. I do not want to downgrade the agent version since it will be against compliance but still struggling to make it work with agent 6.1.1.. Does anyone has any leads what I might be missing to check ? I could really use some help !
