Vista Server 5.x
Cause
There can be several causes for this issue.
A common issue with this situation is the Vista database has been restored from site without the Lonworks NL220 or LonMaker database.
When the Vista server is opened it is unable to contact the Lonworks database and repeated attempts cause the server to hang.

It is possible to prevent the Vista server communications as well as other parts of the Vista server communication.
Reference TAC Vista dll Manager to download a tool from the Community that will allow you to disable DLL files and find the cause of the issue.
If you are seeing the scenario as stated in the above cause, you would disable Option "10: Network communication" and "11: Field bus communication" in this tool then select the Update button
You must remember to enable the options once you have finished with the site database.
If you forget to do this the Vista server will not function correctly when you want to run a live database.
