Assuming that you are using the public Groove infrastructure and not
something that has been set up by your enterprise, verify that you can get to
http://blugro1gms.groove.microsoft.com/gms.dll with a browser. If you can
get to it with a browser you should also verify that other network clients
can get to it. Try telnet.
telnet blugro1gms.groove.microsoft.com 80
then type “foo†and hit return. You should get error output like this:
HTTP/1.1 400 Bad Request
Content-Type: text/html
Date: Thu, 08 Mar 2007 15:47:18 GMT
Connection: close
Content-Length: 35
<h1>Bad Request (Invalid Verb)</h1>
Connection to host lost.
If you do not get this output then you should look at your network security,
DNS or local client firewall software.
