RWW (TS Gateway) Freezes - SBS 2008

I have an SBS 2008 Standard server.  Remote Web Workplace has been working fine until recently.  Users can connect through RWW without issue.  However, after a few minutes of work the connection freezes.  TS Gateway Manager shows the connection is still active, but the screen is frozen.  The user has to disconnect and reconnect and remote system is reconnected again.  There are no event logs until the user disconnects.  This happens FROM any computer and TO and computer and with any user logon.  It freezes on Windows 7 systems and XP systems on on both ends of the connection.  I have tried different versions of IE with no better results.  It will eventually time out if the user doesn't disconnect and reconnect.  They also have a Cisco ASA 5505.

thanks

Have you run the SBS BPA on this server, have you fixed everything it found?

Yes
When is the last time you updated NIC drivers?
Are you running a true Single NIC (not teamed dual ports)?
Is your local subnet 192.168.X.X?
Have you looked at Task Manager when this occurs?
can this happen with just one user connected?
I'll check on the drivers. Single NIC on 192.168 subnet. It happens with one user or many. I'll let you know on the driver.
If you have not done so...download and run the SBS BPA and fix anything and everything it finds
You don't have IPv6 disabled do you?
Have you tested the internet connection? Often RDP session dropping are caused by a poor performing connection. Run some test via ping -t <host> for the remote side for several minutes. See if they are dropping packets. Anything more then 1% lost is typically an issue with your ISP. Since multiple users are having this issue it's most likely the office's connection that's the cause.
I have updated the NIC drivers (along with the bios and the chipset) to no avail.  BPA is clean and IPv6 is enabled.  I am still trying to sort out allowing Ping through the Cisco ASA.  I'm not a Cisco expert, so I am waiting on my Cisco guy to work on that.  What's odd is that when I RDP direct to the server it typically doesn't disconnect.  Only when done through RWW does it dosconnect.
Is the ASA doing anything other than acting as the firewall and doing port forwarding?  i.e. proprietary VPN connections?

I ask because if not, it would be an interesting test to replace the ASA with a simple 40 dollar Netgear consumer router and reconfigure port forwarding and IP settings and see if the problem continues

I had to  replace a CISCO unit in an SBS 2003 because it wouldn't allow Vista or Windows 7 machines to get DHCP addresses from the SBS server...even on the LAN...just a thought
No, there are are 3 locations with the cisco units. In fact, the owner has one at his home an connects via rdp over VPN without issue.
routers can be funny with certain protocols  RWW is slightly different and used different ports than RDP

Just a thought

Let me know if this still happens after the nic drivers are updated
Yeah. That was my thought as well. The drivers are updated, but I'm still having the issue.
I'm increasing the points to 500.  Any other thoughts out there.
Also, I am now starting to get this error.  I have checked that the correct certificate is bound to TS Gateway:

An internal error has occurred (error 50331656). For more information, please contact your network administrator or Microsoft Product Support.
I could still use some help on this if anyone has anymore input.  thanks.
have you run the best practice advisor?
yes

We upgraded the OS on the ASA5505, changed the MTU from 1320 to >1500 and changed the management port to 4433 so it wouldn't conflict with 443 for TS Gateway.  Thanks Chris
Ahhhh, excellent news
