After installating and configuring NetBackup Plugin for vCenter, the plugin screen is blank. They are no errors reported just a blank white screen where the plugin should be seen.
The issue is caused when using underscores "_" in the host name of the vCenter plugin. Internet Explorer does not play well with hostnames with underscores in the name.
A valid hostname cannot contain an underscore ("_") . Valid hostnames can contain only alphabets [A-Z], digits [0-9] and hyphen [-].
Per Hostname guidelines (http://en.wikipedia.org/wiki/Hostname):
"While a hostname may not contain other characters, such as the underscore character (_), other DNS names may contain the underscore. Systems such as DomainKeys and service records use the underscore as a means to assure that their special character is not confused with hostnames. For example, _http._sctp.www.example.com specifies a service pointer for an SCTP capable webserver host (www) in the domain example.com. Note that some applications (e.g. Microsoft Internet Explorer) won't work correctly if any part of the hostname contains an underscore character."

This issue may also occur when using domain names with two characters.
Rebuild the NetBackup Plugin for vCenter using a hostname that does not include an underscore "_" character and the hostname must be longer than two characters.
