Unexpected! I have been receiving many emails regarding "810003c1: We were unable to sign you in to the .Net Messenger Service" issue in Windows Live Messenger.

Unfortunately the truth is Microsoft has shut off the Windows Live Messenger IM for users in the countries embargoed by the US hence Microsoft no longer offers Windows Live Service in the following countries:

* Cuba

* Syria

* Iran

* Sudan

* North Korea

Fortunately, there is a workaround for this "810003c1: We were unable to sign you in to the .NET Messenger Service" error. Just follow the below steps to access to get rid of 810003c1 error.

1. Login to your Windows Live/hotmail account using your username and password.

2. Under your account, click on Registered information link.

3. In the following page, under Home Location section, select a country name other than Cuba, Syria, Iran, Sudan, and North Korea. Click Save button and restart your messenger.

4. That’s it!

Note that you might get the same 810003c1: We were unable to sign you in to the .NET Messenger Service error even after the above workaround only if Microsoft starts blocking the users from the above mentioned countries using the IP address.

Thanks to arstechnica.com for this workaround.
