Hello!
I encountered a strange problem with TFS 2012.3 - i can't connect to tfs web services from my work computer (eg. witadmin, TFS powe tools, etc...). Some other computers in LAN have the same problem, but not all.
I used Wireshark to check network and found out that the network is working properly, all the network packets reach the TFS server.
I guess the problem is somehow connected with ntlm authentication (look at the WS dumps below). I'm confused, please help.
There dump of witadmin command from my machine:
witadmin exportcategories /collection:http://server.loc:8080/tfs/RIAS/p:TEST /f:"E:\categories.xml"

There the same command from "healthy" machine:

I repeat, all the traffic is same on both client and server machines.
EDIT:
When I try to enable and disable kerberos in admin console on the server then all work properly from my computer ONE TIME. Magic.
