View 5.3.1 Pool Deployment Issue

I am building up a View Test Environment. I've got everything built up, but am at the point of building the Pool.

View clones the Base Image, makes the VMs with the correct names and seems to add the machines to the domain correctly. Machine accounts are made in AD.

Connection server says: View Composer agent initialization state error (18): Failed to join the domain

Problem is, the VMs are conencted to the domain. I can logon as a domain user on the VM's no issue.

I am using Connection Server 5.3.1-build 1634134

Agent is version 5.3.1-build 1634134.

I don't know what logs to post and where to find them to give helpers all the information.

Thanks,

Robert Birch
