Clients can't access server

Experts,

OK, this has been a three day journey that I thought ended happily, but....

To make a long story short, deleting a program from the server caused a registry hive error. Fixing that caused an lsass.exe error. Either way, I couldn't boot into the OS. I installed SBS on another drive and was able to access a backup. Given the error seemed to be coming from the System32\Config folder, I just overwrote the Config folder with my backup. Everything was perfect then. I then deleted the temporary OS and formatted that partition.

The server is the DHCP, and it is giving out IP addresses and DNS and such to all the clients. They are able to obtain Sharepoint and access the Internet. All of them can ping the server. But, they can't access any files from the server. They always get the don't have permission error.

They all seem to be on the domain when you look at their computer name and with the other things they can do.

I am not sure if this is an Active Directory issue or DNS or what.

Any ideas?

Thanks.

Bert

I just opened Outlook, which uploaded all of its mail from Exchange.

Hi Bert.
On a problematic client try running NetDiag and GPresult and see if there are any connection errors.
I would also run DCDiag on the SBS. One of those may flag an issue of some sort.
NetDiag is specific to the OS:

GPResult is built-in and DCDiag can be downloaded from:

Thanks Rob,

I will give it a try. I had to reboot it and it has been stuck on Preparing Network Connections for going on 15 minutes. Gotta admit that's pretty patient for me.

:-) yes it is.
Workstations will hang at that point if DNS is not configured correctly, but usually 5 minutes max. Give it time.

Well, going on 20 minutes on preparing networking connections. Should I do a hard reboot?

Some SBS 2008's will take 15 minutes but if your server is usually 5-7 minutes I would. If you can't log on second time see if safe mode will work. Hard reboot is hard on databases like Exchange and Sharepoint, but if necessary........

I have a VM also, which may show an IP address.

I am assuming 192.168.1.100 is the SBS. If so it looks to me like this machine has lost its trust with the DC/SBS.
Is it possible to remove a problematic machine from the domain and rejoin? If so make sure you follow TechSoEasy's instructions:

I figured it out. The problem is I guess I have been lucky for three and a half years.

Part 1: After having several issues with the NIC cards on the server, I decided to simplify tihngs. When I ordered the server, I wanted two NICs just to give me the option if I wanted the two NIC setup. I didn't know it already came with two embedded Broadcom NICs on the motherboard. This meant four NICs -- definitely overkill. Well, tonight I took the card out which had the two Intel 1GB NICs, even though I wanted those. But, I couldn't quite rip out the ones on the mobo. Plus, I just wanted two connections on the back.

Part 2: I had always wondered why one of the Broadcom NetXtremes was labeled Network connection and the other was labeled Server Local Area Connection. Anyway, the Ethernet cable was plugged into the first one. When I changed it to the LAN connection, everything worked.

I guess I always thought you just decided which went where by IP address or whatever. Maybe I am completely wrong, but it fixed everything immediately.

Good to hear.
I assume you haven't actually changed which NIC was connected to the LAN? If you do it can create real problems. You need to use the Change Server IP wizard and then run the CEICW. Sounds like that is not the case and you are all set.

Having removed NIC would have been good information to have though  :-)

True, but it's hard to know what is important when you don't know that you don't know. Make sense?

Ummm....make sense with me, lol.
