Windows 7 lost access to shared drives on Windows 2000 servers
I have been using Windows 7 Pro 64 bit for about 6 months with no problem connecting to shared resources on Windows 2000 servers. Following last critical update from Microsoft I lost access to those drives. Rolled back to restore point and everything ok except I didn't turn off auto update in time and critcal update installed again. Now it won't let me go to restore point as something is corrupted. What can I do: I can connect to a shared drive on an Windows xp machine. I can connect from the windows 2000 servers to a share on the Windows 7 machine. I can connec to the internet. I can see the Windows 2000 servers. What I can't do is connect to the shared drives or printer on the windows 2000 servers. The message I receive is that I don't have the necessary permissions. I've deleted the user name on the servers and recreated it to no avail. I've created a new user name on the windows 7 machine and servers with no success connecting. I've tried turning off password requirements under Windows 7 advanced setting to no avail. The network is hard-wired and consists of 4 machines and configured as a workgroup. Any ideas besides spending days reinstaling windows 7 and all of the software programs?

Try disabling UAC on the windows 7 machine and reboot.

UAC was already turned off. I confirmed it again after your suggestion.

Ok so let me maker sure I go this right UAC is off and everything works fine except you can not access the windows 2000 shares from windows 7. When you attempt that you get a permission error. Ok do you have any firewalls active even the built firewall, if yes try turning the firewall off. If that gives you access then it is a firewall config problem.

Another thing to check would be the network location, you want that set to 'work network'. Control Panel\All Control Panel Items\Network and Sharing Center Network Work Network

Yes, UAC was already off since installion of Windows 7, I confirmed it after your suggestion. I turned off the Windows 7 firewall, rebooted and same issues. I had previously bypassed the router firewall by hooking the computer directly to the switch where the Windows 2000 servers reside. Thanks for the suggestion about the firewall.

Yes, I confirmed that the network displayed is Work network instead of the Windows 7 home network. Thanks

OK and you still get the same error ? hmm, alright then look at the account permissions is the account your using an administrator and only and administrator account on both machines ? Something in the back of my head still tells me this is a firewall/port blocking type issue.

Yes the accounts have admin rights and I've also tried it with the main administrator account. At first I thougth it was a corrupt user profile and started trying other user names. I than started thinking about the computer account itself being corrupt and reconfigured the network settings several times to no avail. Before I bypassed the router I rebooted it several times thinking about the firewall, etc. i have heard rumors of some routers not supporting windows 7, but it was working with no problems for quite a number of months.

"Yes the accounts have admin rights and I've also tried it with the main administrator account." Not quite what i meant, this account/s need to be a member of the administrator group and only the administrator group, they are are a member of and 'administrators' and 'users' for example that can create permission issues. But I think you already know this. I still think is this some sort of network port blocked issue. I've seen similar things happen in XP and I'm racking my brain to remember the details.

I have a similar problem, though i just have a small home network, and the problem is selective, and it's ____ me off. I have a bunch of computers, ranging from windows 7 to windows 98, my 2 main computers are windows 7 and 2000 (home premium and professional, respectively). before I was able to access by windows 2000 computer from the windows 7 computer, but now I can't. It just says that the credentials are bad and tells me to re-enter the password. I know I can access the 2000 computer through the network because I have an XP laptop that can log in to the computer and access the files, and I can log in to another 2000 computer (also professional) from the windows 7 computer. Though I can get access if i try it in reverse (2000 accessing 7). It's a wild guess, but I'm thinking it has something to do with the fact that both computers have the same password, and windows 7 thinks i'm trying to log in using the local password and not the remote password, though I see network activity every time I hit enter. also, I tried changing the password and adding user accounts (I set them to administrative rights) but no luck. the network is trusted and is set as a home network. this is a real pain in the ____ because I needed that connection. also, my parents have a windows 7 home premium laptop, and an XP desktop, though the laptop can only see my computer (the 7 computer) and not any of the other computers. I tried using a hardwire but no dice, though McAfee saw the other computers. I told it to trust the network but windows would still not see the other computers.

TheEdge2 I re-read everything and it brought a couple questions to my mind. 1st is the account your using on the XP and win7 machine the same user name and password ? 2nd If it is a 2000 server have you tried adding the win7 machine to the domain ?
March 23rd, 2010 5:26am

Several of the accounts had the same password, but based on your suggestion I changed the passwords so they don't match. The Windows 2000 servers were a domain and one of the first things I did when having the problem was delete the windows 7 computer account from the domain and add it back. That was one of the first places I thought might be the problem. Since than, in desperation I domoted the Win 2000 servers to stand alone workgroup servers and now have the network setup as a simple workgroup. Thanks

No that wasn't a suggestion, it was a question. What I was getting at; is there an account lets call it [admin1] on the xp machine for accessing the 2000 share and everything works fine. Then creating the same account (with the same password) on the windows 7 machine. This eliminates account issues and leaves the problem plainly with the win7 machine itself.

Hi, May I know the exact error message appeared when you failed to access the shared resources on Windows 2000 servers from the Windows 7 client? Firstly, please adjust the sharing settings on the Windows 7 client: 1. Go to “Control Panel\All Control Panel Items\Network and Sharing Center\Advanced sharing settings”. 2. Under “File sharing connections”, select “Enable File Sharing for Devices that Use 40 or 56-bit encryption”. 3. Under “Password protected sharing”, select “Turn off password protected sharing”. 4. Save the changes above If it persists, please also try the following on the Windows 7 client: 1. Click the Start Button, type "gpedit.msc" (without quotation marks) and click OK. 2. In the "Group Policy" window, double click on "Windows Settings" under "Computer Configuration". 3. Double click on "Security Settings"-> "Local Policies"-> "Security Options" 4. In the right panel, double click on the "Network Security: LAN Manager authentication level", please select "Send LM & NTLM Responses". 5. Click Apply and OK. Then reboot the computer and see if you can access the share folder on the Windows 2000 computer from the Windows 7 computer with UNC (\\computer\folder or \\IP Address\folder). Hope this helps.

Thanks Nicholas, this was exactly what I was looking for. Your first suggestion section 1-4 fixed it for me. Thanks again! Water Man
