Cannot browse network computers on SBS 2003

We have brand new SBS 2003 with 5 cients licenses setup in a domain envioronment. I have only 4 workstation and 3 network printers that show up when I explore my domain. Recently, the workstations have not been able to map drives or explore my network places. It gives the following error:

Domain is not accessible. You may not have the necessary permissions to use network resource. Contact Administrator...No more connections cna be made to the remote computer because there are already as many connection as the computer can accept.

Now, what is interesting is that the licensing shows that 5 out of 5 are installed whereas I only have 4 workstations. Are the network printers that are plugged directly to the gigabit switch taking up licenses?

This is happinning from all the workstations. The workstations that already have shared drivers to the server are still available and everthing is accesible however if you disconnect that drive and try to reconnect it fails. We dont know when this started happening as we install the printers in the last month or so.

I even disabled the Firewall through group policy as at first i thought that the firewall is blocking file and print sharing ports. All wks are XP Pro with SP2. Also, I noticed that I cannot ping my workstations from server but can do visa versa. When I ping from server by name it resolves but fails.

Is the firewall on server blocking the pinging...no errors on server or wks...clean runnign setup with NATing done by router. All wks point to server for DNS and DHCP.

Any suggestions?

Two possibilities... either one or both may need to be fixed.

1. You do not have the WINS IP address configured on your SBS's NIC configuration which would therefore not get transmitted through DHCP to the workstations.

2.  You did not use the connectcomputer wizard to join your workstations to the domain.

To fix the first item, you need to add your server's IP address to the WINS tab of the advanced settings for TCP/IP.  Then you need to re-run the Configure Email and Internet Connection Wizard (CEICW -- linked as Connect to the Internet in the Server Management Console > Internet and Email).

To fix the second item, you need to follow these steps:

The following needs to be done with the client machine:
1.  Log in with THAT machine's LOCAL administrator account.
2.  Unjoin the domain into a WORKGROUP
3.  Change the name of the computer
4.  Delete or rename the following directory C:\Program Files\Microsoft Windows Small Business Server\Clients if it exists
5.  Ensure that DHCP is enabled and there are  no manually configured network settings
6.  Reboot

Then on the server, from the Server Management Console:
1.  Remove the client computers if it still shows in the Client Computer screen on the Server Management Console
2.  Add the client with it's NEW name using the Add Computer wizard

Then, go back to the client machine and join the domain by opening Internet Explorer and navigating to http://servername/connectcomputer

1. Checked WINS. It was already added in the TCP/IP properties of the NIC card on the server. However, it is not being distributed by DHCP. DNS is pointed to the server ip and is what is being distributed, along with ISP DNS address. However, I dont think I have a forwarder setup. I dont think the forwarding is what is not allowing me to ping my workstation although it resolves the name. I still cannot browse.

2. All the computers were added using connect computer wizard...Have not tried what you said yet

3. What is the difference between ICF and Windows Firewall. I know I have been messing with the firewall. What is strange is that even when I am logged in a domain admin on a workstation, it does not allow me to map new driver or browse the network but I can do so from the server.

Anything else? I am still puzzled with the license usage. Any ideas there?

thanks for your detailed replies.

1.  How is the ISP DNS being issued by DHCP????  

You need to configure your network settings according to one of the options at http://sbsurl.com/msicw.  You do this by running the Configure Email and Internet Connection Wizard (CEICW -- linked as Connect to the Internet in the Server Management Console).  This will create your forwarders as well as about 50 other settings required to properly deploy your SBS.  See http://sbsurl.com/ceicw for a visual overview.

2.  If your computers WERE joined to the domain using connectcomptuer, then you do not need to follow those steps.  

3.  The Internet Connection Firewall is only for use when sharing an Internet Connection in Windows XP.  You would not be doing this with a domain workstation, but you also don't need to touch the Windows Firewall... it's all managed by the SBS.  Also, you should NOT install the Windows Firewall on the server under any circumstances.  When you run the CEICW you will be asked if you want to use the Firewall if you have two NICs installed.  This is not the Windows Firewall, it's RRAS, and SHOULD be used if you are using two NICs.

If you have a specific question about licensing, please post it separately.

ISP DNS is not being issued by DHCP. DHCP only issue the DNS address of the server and the forwarded forwards the request that it cannot resolve. However, under DNS settings on the NIC card of server, i do have secondary DNS of the ISP.

Got your points.

I have ordered another 5 client pack and will see if it is a licensing issue. I will let you know after installing it.

I am also, planning to setup exchange on the server so I will have to run the Internet Connect Wizard again anyways. is there a way to suppress the Outllook 2003 from being installed since the computers have Office 2003 already.

And how do I go about getting over all their PST file data over to the server or converted into a exchange mailbox.

Also, do you have any guides on installed Premier Edition...just like Standard Edition...specifically on ISA that comes with Premier.

You should NOT have your ISP DNS IP's as secondary on the NICs.  They need to be entered as forwarders when you run the CEICW.  You can run the CEICW as many times as necessary, so run it now to fix the network settings after you've removed the ISP's DNS IPs from the NICs.

You don't need to worry about supressing Outlook 2003 installation... it won't install it twice.  It knows that it's there.

You probably should read the guide on migrating from peer-to-peer to SBS, which will help you understand how to migrate email as well.

There's plenty of documentation about SBS right there in your system.  Open Help & Support.

If you want a good book to have as a companion guide, then I'd suggest Eriq Neale's Small Business Server Unleashed:

My server has Two NIC cards. Some days back, I was messing with the second nic card to setup a VPN tunnel and must have enabled it. You cannot have two NIC card enabled on the server. The second NIC card was getting a DHCP address from the server. By disabling the second card problem was resolved.

Also, turned off Computer Browser service on all but one computer in the network.
