SBS 2003 R2 ICS and Remote Access problem

Hi bctf1,
Lets try the simple fix first.
Make sure Remote Access Connection Manager Service is running.
Install or re-apply SP.
Make sure you're  logged on as an administrator or have administrative privilege to setup the VPN.

This is the suggested fix for this exact problem that I found at http://www.chicagotech.net/vpnissues/vpnunavailable.htm 

Let me know how that works.

Also please check the event log for any of the following messages and post back.
Cannot load Remote Access Connection Manager. Error 711
The Network Connections folder is empty.
The Internet Connection Sharing and Internet Connection Firewall (ICF) services do not start because of a dependency failure.
System log Event ID: 7023 or 20035

Hi mc, thank you for your reply. I did get VPN configured and working using remote access and rras. However after the first server reboot, the ICS service would not start and it effectively broke my lan as a result as referenced in my post above. After disabling remote access via CIECW and disabling remote access my lan was restored to normal function.

Thanks,
Brad

so do we still have an issue?

Yes, we still have an issue because I had to disable remote access so my lan would function. Perhaps re-reading the middle paragraph in my original post will make things clearer.

There were 2 system events that repeated after remote access was enabled and my server rebooted for the first time yielding an inoperable lan.. They appear below. Remember that after remote access was disabled, my lan worked again and the events below did not reappear.

system event 7023, source - Service Control Manager - The Windows Firewall/Internet Connection Sharing (ICS) service terminated with the following error: The requested resource is in use. Numerous instances until remote access was disabled.

system event 32009, source - ipnathlp - The Windows Firewall/Internet Connection Sharing (ICS) service could not start because another program or service is running that might use the network address translation component (Ipnat.sys). This can occur when Routing and Remote Access is enabled. If this is the case, you must disable Routing and Remote Access before the Windows Firewall/Internet Connection Sharing (ICS) service can start. Numerous instances until remote access was disabled.

My primary concern here is not whether I have VPN working because I also have RWW running. My primary concern is the 2 questions that I posed in the last paragraph of my original post:

""I have read that the ICS service does not have to be running on SBS 2003 for normal lan and internet functionality, is this true? Do I have something configured wrong on my server or my workstations, or it simply that with 1 nic, ICS and remote access cannot coexist?""

Thanks,
Brad

Alot of information there.  Click on the one that says:
