Hi when i sign into wlm at work via the adsl connection it wont sign in, comes up with error signin in 80072745 with my laptop, but when i go home and sign onto the same laptop with my wireless 3g connection it signs on. what is causing this problem, i tried so many things, nothing helping.

I did a ggle search for you and came accross this page that might be of some use: http://www.microsoft.com/communities/newsgroups/l...3-0d9dd7c28e88&p=1

On that page it said that some possible reasons behind it are that the messenger server is curently unavaliable or that you might be behind some kind of firewall that is restricting your access to messenger.  Still it might be wise to have a look for yourself nd a more detailed google search too.
