Recently on the discussions a poster bought up they have been encountering issues post citrix license server rebuild.
The user may see the following error when trying to connect:
“Citrix XenApp license acquisition error (-25): Unable to acquire a license from (<server name>) server. Please contact your system administrator or open Event Viewer for more details.”
Sure enough when doing a qfarm load on the systems they were getting a load value of 20000 meaning the servers were unable to acquire a license for the user. Poster made the point their host name was rebuilt with the same name as previous build.
Ultimate fix turned out that not only does the name need to be same but the whether the original name is in capitals or not makes all the difference too. So take note if ever doing a rebuild to check the case sensitivity of the host name of the license server as it won’t provide a license unless its rebuilt as was.
