Application notification messages error

[BigBrett]

Since updating to the 10.1 version of Vault Pro, I have been receiving the occasional message that there was an error retrieving application notification messages. The call stack is as follows:

If you use the GUI client, do you receive the same error?

Using a browser on this same machine, if you (correct for the URL in the error log), what does "http://web.address/VaultNotifyService/V ... rvice.asmx" show? Does it get the VaultNotifyService Service Description page?

If that works, it may be worth checking into the vaultnotifyservice.txt file on your Vault Server (by default it is stored in %WINDIR%\Temp\sgvaultnotify\ to see if there are any errors in the Notification server configuration.

Note, if you do not use application notifications, you could also turn it off from within Visual Studio ( Tools -> Source Control -> Vault (Professional) Options -> Advanced Options -> Notifications, "Enable Application Notifications"

I don't use the GUI client very much, so haven't noticed anything in that regard.

The service description page dos display.

The log file has a number of continuing errors as follows (generic extract):

I have work item notifications enabled, but done via email. I had some source control watch notifications on but recently removed them.

If you have turned OFF (unchecked) application notifications within your Vault options from within Visual Studio, you shouldn't see any related problems regarding application notification messages. I'll look into see if there's something related to that setting and the error message in the OP.

No need to worry any further about this, it is a server connection problem.

I am working from home using my fibre line to connect to the Vault Pro server in the office. I saw the notification error message while I was working, and also noticed that my server connection dipped at exactly the same time.
