After installing SBS 2003 server, I am no longer able to connect to the server remotely. We are also no longer able to use Outlook Web Access.

Might need to enable remote desktop on the server. Also double check the routers firewall rules to make sure the rule allowing RDP is point to the correct IP of the new server. Same for the pop3 and smtp for remote mail. You can also setup OWA.

I totally understand what it's like to spend so much time on a project and the need to step back from it a bit... but I need you to help us out here because while you said you are surprised that you can't access it... I'm trying to even figure out what the problem is.  

I mean, I could answer... did you try using a compter to access it?  But I didn't want to be that mean to you after such a long, hard weekend...

So... how about giving us a clue as to how you are attempting to do this and what the error messages are?

I am trying to use remote desktiop to access the server throught the terminal services capability of servers for remote administration.  
The IP address and the name of the new server are identical to the old server, as it was my desire to minimize the number of problems.  The old server is off the network, so there are no IP or name conflicts.  The new server is, of course, the domain controller, so there is not conflict there.  I have remote desktop enabled on the server, and I verified that the domain security was set to allow access to the server through terminal services.  
The firewall is still set up to allow access through remote desktop.  I have to believe that it is an SBS2003 setting that I am just not familiar with.

Thank you.

This may be set up already but,

Forward 3389 to server
Make sure "Remote Access" is checked in My Computer/Properties/Remote tab
Make sure Terminal Services is started (start...run...services.msc )


For people to get their email remotely...forward ports 80 and 443 to the new server
(Assuming you've ran through the wizards)

For email to actually flow to the server, forward port 25

for remote web workplace forward port 4125

hope this helps

Tom-J-Lael - thank you for a nice, concise list of suggestions.  The firewall settings have been in place for quite some time, as I was able to do what I needed when the Windows 2000 server was installed.  That is why I think there must be something in SBS2003 that I am overlooking.

Thanks.

You need to run through the wizards, and make sure Terminal Services service is started in the Services.msc

msobey,

So, if I understand you correctly you had a Windows 2000 Server based domain and you replaced that with an SBS 2003?  Since you used the same name I'd suspect that you didn't do a formal migration but rather just installed the new server in place of the old.  Or was your old server a Small Business Server 2000?  Because you mention Outlook Web Access.  

Have you ever installed and configured a Small Business Server 2003 before?  Did you run all of the installation wizards that are included on the To-Do List?  (Especially the Configure Email and Internet Connection Wizard and the Remote Access Configuration Wizard).

As a backup solution to remote access...I also use the Free version of LogMeIn software incase terminal services has issues. It also transcends firewalls.

The firewall had inadvertantly been changed to allow only a certain range of IP addresses to access port 3389.  After I opened this port more completely, I was able to access the server remotely.  This issue can be closed.

Thank you to everyone who offered advice.
