Remote Mac Screen Sharing modal hangs up forever

I often log in to my office Mac from home to get files and sometimes to control the office computer via Screen Sharing. My Macs are both registered with mobileme and thus show up in Finder. I normally click the icons in the Finder sidebar, click Screen Sharing and go on about my business. This is done using Back to My Mac settings.

Suddenly, I can no longer do this. When I attempt to connect Screen Sharing, the modal tosses the spinner like it's trying connect. That modal sticks that way forever. It will remain in front of all other windows. Even if I quit Screen Sharing. I have to either reboot OR open Activity Monitor and quit the NetAuth process.

I can access the file system all day long and move files around. But Screen Sharing has ceased to function.

I have tossed screen sharing plist files. I have reset file sharing, screen sharing, remote access, approved users. Nothing solves this issue.

Both computers are running Snow Leopard 10.6.8

A 443 BTMM port is set to forward to the target computer.

Screen sharing uses VNC port, 5900. You should get more info in the system.log, maybe is ARDVNC agent crashing there?

You could try repairing disk permissions. I've seen that fix a lot of issues when things don't work. You could also try Logmein instead of using BTMM.  BTMM is really nice, I use it, but it's always been a little flaky and hard to troubleshoot. You might also try resetting your router and/or cable (or whatver) modem.  

I had a deal once where BTMM was working and then it stopped. During the course of troubleshooting, someone had me change the external DNS settings from what I was using (provided by my ISP) to the ones used by OpenDNS.  After that BTMM started working again...for a while. When it failed again, I changed the DNS settings back to the ISP ones and it started working again.  Since that time, I've not had any issues and that was a year or two ago.

Yesterday eve, I was able to control the screen on my older G5 (in the office) from home. Attempting the iMac, failed as described above. When I'm sitting here in the office on the same network, I can control the iMac. So, clearly the 443 port forward I'd set means nothing, otherwise I wouldn't be able to access the G5 which is behind that same router.

robertcerny, do you mean to look that they system logs from the target computer or the MBP I'm trying to connect from?

jhyiesla, i've run the perms repair on the target computer and will try again this evening.

ultimately, I wiped out screen sharing perms, turned off all sharing. rebooted, reset Screen Sharing, made sure not to select Remote Management. All has been well since then.
