Unable to connect to network shares on SBS 2003 from Windows 7 client

Hello,

We have a weird problem.
On a SBS 2003 network with about 10 client pc's (Windows XP's, Vista's, & Windows 7 clients). there is one client pc that lost its connection to the SBS server, all other clients work fine.

Everything worked fine for a few months but this morning the client couldn't access any shares.

- I can ping the server hostname and IP adres
- I can connect to http://server/Connectcomputer 
- I added the server IP manually in the dns settings
- I tried a winsockfix
- I tried a /flushdns

ipconfig /all

The only thing that works is a system restore, but this is the second time I had to do this.

hop you are right IT looks like your external DNS server don know your server so if PC ask for server it can't connect. Try to change local DNS on this PC to primary DNS 192.168.1.2 (if it is DC if not give DC address as DNS)  and secondary 94.140.160.200.

if don't help try to give PC out of DOMAIN and connect it back again BUT DELETE COMPUTER ACCOUNT IN AD
jop and try //SERVER_IP/SHARE_NAME to be shore that problem is DNS

I've allready tried to set the primary dns to 192.168.1.2
it works, but after I reboot it forgets my settings ??


\\192.168.1.2\Data (working share) doesn't work
\\server\Data also doesn't work.

The weird thing is that all the other clients get the correct dns data and have no problems connecting.
hmm did you checked PC account in AD ? If the pc is in right group and if it is not disabled?

if you don't have weary important settings on it try to give it out of domain and back in

1. Take PC with network wizard out of domain
2. Turn PC off
3. Delete the pc accout in AD
4. Turn PC on.
5. add pc to domain
6. reboot and try
HEllo,

I checked the account, its in the correct group and is not disabled.

Taking the laptop out of the AD, deleting the computer and reset doesn't work either.
I cannot delete the user, it had to much data..

For the record, this user logs in on 3 diffrent computers with the same user. the other 2 work fine.
whats the win 7 version you are using? also please make sure the client time and date is correct.
Hello, its Windows 7 Pro - SP1 and fully updated.

The time is correct, I even synced with the ntp of our isp.
hmmm can you access to the computer from server? Try share folder on problematic computer and try accost form other pc and server.

Do you using some special firewall or security SW on PCs?
Hello,

I didn't try that yet, i'll do it this afternoon and get back to you.
I'm not using any firewall accept for the build in Windows Firewall that is controlled by the server. I am using Panda Cloud AV (free) for antivirus but that shouldn't be a problem.

If i boot in safe mode with network access I can access the shares on the SBS.
So I think there is only service or application that is preventing me from connecting to any shares but I can't seem to find out which one
Can you send us list of installed apps ? I can tell you then if someone make bad to my customers.
is it possible for you to disable the firewall and AV ?

hello,

Sorry for the late reply, I was on vacation.
The solution was to reinstall the cliënt pc. I didn't have time to check every application to test.
