Vista - Remote Desktop does not connect, no error, nothing

Hi,

I have been connecting to my work computer via remote desktop for quite
sometime now without any problems.

But now I cannot connect anymore.
The weird thing is that I get no error message, nothing.

The 'connect' button is disabled for a short while, then after about 5
seconds it is enabled again. No errors, no nothing. If I enter the wrong IP
address I get an error message.
I can ping work IP address.

So what could be the problem?
Why am I not connecting and why am I not getting any errors?

Thanks

Simon

have you tried using another machine and the problem did not follow to
the other machine?

Well, I can check at work tomorrow, it is possible that something has
changed.

But having said that, why would I not get any error messages?
When I try and connect to another machine, (one that I do not have
permission to), I do get an error message.

But in this case I get nothing, no error, no warning, nothing.
