We are getting a lot of "unable to detect changes error".

We can succesfully connect to TFS as our checkouts have no issues but we are getting errors li9ke the above all the time.

[Sergey Podobry _Stellarity Software_]

Actually there is only one reason to get the exception - when the TFS server is not accessible (or not responding for 3 seconds).

If you want to confirm network issues

I'm thinking about a script that will ping your TFS server and write a log. Also special monitoring tools can be used. I can help you with that if you require any assistance.

If you want to suppress the errors

It can be done. I can introduce an error counter and trigger the exception only when the counter exceeds its limit.

The issue is discussed here.
