Hi Mark,
Thank you for posting in SBS newsgroup. Hi Susan, Thanks for your input.
>From your description, I understand you want to know how to let the
anti-virus program pass the firewall. If I have misunderstood your
concerns, please do not hesitate to let me know.
Regarding Windows Firewall, by default, the firewall is disabled on SBS
because the SBS uses the Basic Firewall in RRAS to protect the LAN and the
SBS itself. Also, since SBS host many services, if you enable the Windows
firewall on SBS, it will result in many problems. When you enable the
option, then a Windows Firewall bounce box will occur which tell that you
can not enable the firewall.
If you want to add program exception, please try the steps of the article
http://www.sbslinks.com/group.htm which Susan has provided.
Please also refer to the section Configuring Windows Firewall for a Windows
Small Business Server Environment of the following document:
http://www.microsoft.com/technet/prodtechnol/sbs/2003/deploy/sbs_xpsp2.mspx
You may also need to contact the anti-virus software provide to check which
port is needed or which application is needed to be added to the exception
list.
I will look forward to your reply.
Best regards,

| Hi,
|
| I have just upgraded my SBS 2003 machine to SP1 via Windows Update. It
has
| gone pretty well! I do have one problem, however.
|
| I have SBS standard edition. My machine has two NICs. One connects to a
| firewall and then to the internet, the other connects to the LAN so all
| clients connect via the server, which connects via a dedicated Firewall.
|
| Now my anti-virus program sits on the server also, and all the client
| machines connect to it for updates and centralized reporting. The clients
can
| no longer see the anti-virus server, and I need to add an Exception to
the
| Windows Firewall on the server machine to allow the LAN-side machines.
|
| Now here is my problem. When I run Control Panel / Windows Firewall on
the
| server machine I get a dialog:
|
| Windows Firewall cannot run because another program or service is running
| that might use the network address translation component (Ipnat.sys).
|
| So, how do I add a program as an exception?
|
| Thanks for your help,
|
| - Mark
