Cisco VPN in XP causes OSX to crash

My company just recently went from the standard Cisco VPN client to a web-based version. The last few times I've tried running in on XP via parallels, it crashes not just Windows, but my Mac as well, forcing me to reboot.

I'm running XP SP3 on OSX 10.5.4. It only happens after I connect to the VPN.

Anyone else have any problems like this?

 

Would you provide more details
Web solution you are trying from Windows or from Mac OS?
What is in logs
* Archive of /Library/Parallels/bugreports/
or ~/Library/Parallels/bugreports/

* /Library/Logs/panic.log
or ~/Library/Logs/CrashReporter/Parallels.crash.log from the Mac side;

 

I can't find anything in the logs for yesterday at all. The system just totally froze with the window that says to hold the power button down to turn off the system.

After rebooting the machine, I did have it send reports to Apple, but I can't find a record of that.

I was running the VPN on the Windows side. It's a Web based java app from Cisco running on IE7. My Windows VM seems just fine on it's own, as I use it constantly. And I've used the same Cisco client in the past with no problems. I f not for the fact the the VM crash took down OSX in the process, I wouldn't even be too concerned.

EDIT**
Sorry...looked in the wrong place. Parallels is not recording any logs on the crash, but the panic log is listed here below.

Could you check how it will work in Firefox?

 

hmmm...

So far it's working fine via Firefox. Must be an IE issue causing everything to collapse.

 

Ok, try to add, site to trusted, and may be looking Cisco forum will get some clues

 

I've been looking so far without success, but with it working via Firefox, I'm good. Thanks for the help.
