Is the server using a static or dynamic configuration?.Gather the server’s IP configuration information.Can you ping the local loopback address?.My point is this, the error you see is not always the error you have! Don’t forget basic network troubleshooting steps. This was resolved by added the new server’s IP address to the appropriate firewall rule. One XenApp server had been replaced and the IP address of the new server had not been added to the firewall to allow its traffic through.

A firewall separated the XenApp servers from the Citrix and Terminal Server license servers.

This issue does not affect DNS running on Windows Server 2003 and later. There was only one Active Directory site involved. All other Domain Controllers were reconfigured to point to the central Domain Controller for primary DNS and to themselves as secondary DNS. This was fixed by designating one Domain Controller (the one holding the PDCe FSMO role) as the central Domain Controller. This created DNS Islands and not all Domain Controllers had the host record for the Citrix license server.

The first course of action would be to follow the relevant Citrix Support Knowledgebase Articles:

Citrix software was everything from Presentation Server 4.0 to XenApp 5. There was not any typical correlation between the servers. Over the past few months I have come across several seemingly unrelated issues that all had one root cause.
