Windows Server 2008, scanner can't connect to server

I'm experimenting with Windows SBS 2008 for the first time and I've created a problem with a Sharp MX-2300 being able to access my server.  I was attempting to setup a VPN and in doing so, Routing and Remote Access got enabled.  Immediately all my client computers got disconnected from the server.  In my idiocy trying to troubleshoot this problem, I ran into the Network Policy Server Role, which I didn't really understand and was suggested that this could be causing the problem.  My genius self decided just to remove that role in an attempt to fix the problem.  So I di d so and of course this did not help.  I did eventually disable Routing and Remote Access which immediately allowed the client computers to connect.  This is not my question, but if anyone could explain how setting up a simple VPN could have disconnected all client computers from the server, I sure would apprecaite it.  I've setup VPN w/ Server 2003 more times than I can remember and am surprised I've had this much trouble w/ 2008.

So, once I disabled Routing and Remote Access, my clients were able to connect, but I had a few server based programs that were no longer connecting to the server.  I reinstalled the NPS role and made a few program specific tweaks which seemed to solve all of my problems but the multi-function scanner.  I have a Sharp MX-2300 that used to scan files directly to a shared folder on the server w/o any problems.  Now, when I try to scan, I get the following error on the scanner:  Selected Servers are not found, consult your network administrator.

I made no changes on the scanner during all my medling on the server.  For testing purposes, I changed the scan to folder on the scanner to a folder on another computer and it scanned correctly.  I've also tried creating a new folder on the server and disabling the firewall on the server (I believe I'm doing this correctly as I'm not terribly familiar w/ 2008).  None of which helped.  I'm thinking my problem has to do with some NPS policy blocking access, but I'm not really sure.  

Any help would be greatly appreciated.

Sometimes the most basic resolutions are the ones we overlook, especially when we are technically inclined.  Did you bounce (power cycle) your server and then your scanner?

Yes I did, several times

Can you install Wireshark on your server?  If you can, start trapping right before you try to scan a job.  See if it ever tries to talk to your server.  In this way you can immediately know what direction to start looking...

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

I'm not familiar with Wireshark.  Let me read up on it and i'll give it a go.

It is a freeware packet capture tool...

I'll try that tool shortly and let you know how it went.

Sorry, I haven't abandoned this question.  The office with the issue always closes for three weeks this time of year.  They resume business week after next and I'll be getting to this problem when they return.  Thanks for you patience.

OK, I installed wireshark and have a few log files saved.  I'm not really sure now to make them out though.  I do see a request from the IP address of the scanner.  Please let me know if there's something specific I should be looking for in the log file.

I also notice that the server isn't present in the client computers when you try to browse the network via My Network Places.  The clients can browse directly to the server w/o any problems via \\servername, but the server is not present when browsing via My Network Place.

Thanks for your patience.

What mechanism does the Sharp scanner use to scan and deposit the scans on a shared folder?  Did you have to create a service account for the scannere to authenticate with AD for share permissions?  If so, can you verify that the service account is not locked out and that it has permissions to the share?

It users the standard smb protocol.  It stores the AD username/password.  I'm used several different accounts that I know have the proper permissions and none of them work.

Do you use the web interface to set that up?  If so, could you post a screen shot of the Address Registration page?  If you can't do that, please make sure it is addressing the server by IP address and not by computer name.  Also, the username and password are for a LOCAL (not domain) user (not group) account.  So, on your server that has the share, you will need a local user account with the needed permissions on that share to place in that setting on the web interface.

If you think it will help, I'll be happy to post the screen shot, but I think that's unnecessary.  I'm very familiar with this machine, having set it up for several other clients.  I've also successfully set the machine up to scan to another computer in the meantime.  I've tried using several usernames and passwords, including the Administrator password, which is local.  I have also tried addressing the server by IP address.

I'm not sure if I mentioned it clearly above, but everything was working fine w/ the scanner until I made the routing and remote access changes as described.  Only afterwards did I experience this problem.

It is possible that RRA changed your local firewall settings on the server, but I thought I read above you had it disabled.  If changes were made (including enabling it), a second look may prove fruitful.  But, if it is indeed disabled (and you would see very clearly in the Firewall setting from the Control Panel), then that should not be an issue.

I know RRA was definitely disabled.  I'll check the firewall settings soon.

Turns out it wasn't the firewall.  Somehow, a second A record for my server name was being added by RRA, I'm guessing.  That second A record for my server name was pointed to the VPN IP address of my server.  I actually figured it out from another question.  I'm posting the link below.  Thanks for everyone's help.
