LCS PIC - unable to add PIC contacts in Office Communicator
Now there are many times we have problems adding contacts so please read this carefully as the problem exposes itself for the user of MSN not Office Communicator (Windows Messenger would likely report the same or similar error, I just didn't test as most customers run OC). Customer may report that...

Surface Pro and Function (FN) key lock
Now that I figured this out, its a really cool feature but for the last week and half its been a real pain. At some point (likely when locking the computer and wiping the keyboard) pressing home and end keys on my Surface Pro stopped working as expected, to the point I put in a request at work to...

Windows Messenger Autoconfiguration with LCS and domain names SRV queries
Interesting customer issue reported in that they could connect using TLS when providing the FQDN but when using Autoconfiguration it failed to connect. Normally when a customer tells us this we know that it is NOT a certificate issue, otherwise TLS would fail when using the FQDN. We can suspect that...

LCS 2003 & Windows Messenger 5 Connectivity
LCS 2003 & Windows Messenger 5 Connectivity Overall the behavior below is applicable for LCS 2005 but given the new feature of Pools there may be some slight/subtle difference, so for now this is about 2003 and I will edit at a later time with 2005 applicable changes (if any). When establishing connectivity...

LCS 2003 and Windows Messenger failing when set for Automatic Configuration with single label domain names
A quick modification to this post is that the analysis is accurate and this is current behavior. Bug/By Design are just semantics but we don't build the DNS query for a single label suffix for the SIP-URI. At this time, the solution is to not use Automatic Configuration or alter the SIP-URI to have a...
