After installing the VUM (vSphere Update Manager) on the vCenter Server, it was indicated that before you can utilizie it, you must first go to the Plug-in manager within the vSphere Client and "Download and Install..." the plug-in for it using that link displayed. When I click the link, I get the following error message:
An internal error occurred in the vSphere Client.
Details: The remote name could not be resolved: ''servername.domain.com'
Contact VMware support if necessary.
Obviously it appears to be a DNS issue, but the DNS seems to be working fine across the network and everything is working fine. Is there some other way of correcting this?
