I have Microsoft Lync 2010 installed on my Windows XP computer. I cannot log in to my account in MS Lync. I tried logging in to other PC and it went successfully with the same username and password that I used in connecting when using my own PC. But I am getting error when using mine. I tried restarting my system for countless times and yet, the error below is still showing. Please someone lend me a hand and help me with this. Thanks.
