TF400324: Team Foundation services are not available from server in Visual Studio 2012

Question

When I open my existing solution in Visual Studio 2012 professional, I got the above error. This used to work but something messed up after the computer is rebuilt.

Answer 1

We solved it by adding a specific exclusion to ESET / Kaspersky AntiVirus for the devenv.exe "C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\devenv.exe"

Its been working great ever since.

I get basic idea from this link
