Update August 29, 2013: I have reproduced this again and am attaching a full crash dump of msvsmon.

When using Visual Studio 2012 Update 1 to remote debug, the remote debugger will crash if I have a solution open when I attach.

Visual Studio immediately reports an error "The network connection to <server>:4016 has been lost.  Debugging will be aborted."  A few seconds later the remote server shows "Visual Studio Remote Debugging Monitor has stopped working."  Interestingly enough, if I "Close the program" the monitor UI is still running.

If I attempt to attach again, I receive an error that a debugger is already attached to the process.

If I close Visual Studio and the remote debugging agent and start over - this time without opening a solution.  I am able to connect without any issues.

-Client (VS) development machine is Windows 8 x64.
-Remote machine is Windows 2008R2 SP1.
-No firewall is involved.
-VS machine is on a domain, with local user account with the same credentials as domain account.
-Remote machine is on a different domain, also with a local account with the same credentials as VS local account.
-MSVSMON is running elevated as the local account
-I am attaching to IIS 7.5 (w3wp.exe) on the remote machine, using x64 Managed .NET 4.0/4.5

I used the VS feedback tool, but I don't see any attachments on the incident. The zipped dump file was ~100MB so I cannot upload it via the web. How can I submit the dump?

I have not been able to duplicate the few times I have tried connecting yesterday and today. I will update the ticket the next time this occurs.
