1. Analyze the virtual machine’s log, there is the “7022” error in the log of the application program, as the following displayed:
It shows that the “Server” service hasn’t started, but the corresponding programs with “Citrix” are all dependent with the “Server” service, so these programs can’t be started, thus the virtual machine can’t register to the DDC. In about 15 minutes later, after the “Server” service has started, the “Citrix” can start now, so it causes the process of the virtual machine registering to the DDC taking a bit long time.
2. The “Print Spooler” manages the entire local and network printing queue, controls all the printing work, starting the “Print Spooler” service depends on the “lanmanserver” service (it supports the computer to print file through network and nominate the channel sharing, the displayed name is “Server”), after the virtual machine’s “Citrix” has installed, it changed the sequence of the system’s starting application program, if there has set the sharing printer on the network, then it will make the “Print Spooler” service starting firstly, and the “Server” hasn’t started, so the “Print Spooler” service can’t start normally, we must wait for about 15 minutes and then the “Server” service has restarted automatically, and finally it can be normal.
3. The firewall is in the abnormal status is also caused by the “Server” service hasn’t started.
