Win 7 Pro x64 Group Policy Error - mapped drives not connectable after a while

Hello,

Thanks in advance for helping. This thing is driving me insane!

Our domain controller is a Win Server 2003 R3, and we recently replaced several workstations with newer hardware running Win 7 Pro x64. For the most part, every thing runs smoothly. We have a shared folder on the 2003 machine that everyone uses to store their data. Everyone logs on to the domain, not the local machine.

The problem happens when a machine is left on for more than one day. I don't know if it is on a regular interval, but I haven't noticed it as such. Eventually there is an error when trying to connect to the mapped drive: "U:\ is not accessible. An unexpected network error occurred."
When trying to browse the server from the Network in the Start Menu I get this: "Windows cannot access \\servername Check the spelling of the name... Error code 0x80070035 the network path was not found."

I get a positive response when I ping the server's name and IP address from the client computer, and vice versa.
I checked that the following services were running on both machines: workstation, server, tcp/ip netbios helper, DHCP client, DNS Client.

The client computer's Ethernet adapter settings uses the server as the Preferred DNS Server in the IPv4 properties [it is set manually].

I tried ipconfig /flushdns on the client, then ran gpupdate in an administrator cmd window, still got an error.
I ran gpresult /h gpreport.html and will attach that file for inspection.

There are some errors in the system event log with GroupPolicy as the source and 1030 as the Event ID.
Sometimes there is an error in the log with NETLOGON as the source and 5719 as the Event ID.

What really makes it aggravating is that it only happens when the client computers are left on for more than a work day. If they are rebooted, it works fine. So I have a work-around, but I'd rather have a solution ;).


All help is greatly appreciated.
Thank you,

_theJestre

One thing that comes to mind, is the connection persistent?

Ie the /persistent flag set on the net use command?

Hi cryptodan,

I don't know. I ran 'net use' in a cmd and pasted the results to this pastebin link:
http://pastebin.com/8RiZdmLq

I don't see the /persistent flag mentioned, does that mean it is off? How do I set it to be persistent, is it on the mapped drive settings?

Thank you!

It wouldn't show there, and it would be on the command line via a login script:

net use * \\server\ password /user:domainname/username: /persistent:yes


the general use of net use just shows the connections made via NetBIOS.

Thanks for the quick responses.

I'm not very familiar with what you are talking about. Are you suggesting I use the line above in a .bat file that is run on log in? If so, how do I accomplish that? And some of the passwords are very sensitive, do I have to include them in plain text?

Thanks,

_theJestre

EDIT: on my computer right now I cannot access the mapped drives [left my computer on all night to try and trouble-shoot this thing], but the net use command shows they are ok. Is that strange?

Are they showing up in My Computer, and what you are stating is that persistent connections is not on. Can you reboot and verify?

How are these drives being mounted first?

Yes, both appear in My Computer and there is no red X. They appear fine in My Computer, but do not work when clicked.

Can you reboot and verify?

If I reboot I will be able to access the drives, but I don't want to reboot because it takes a day or so to get the computer in this state so I can trouble shoot. Let's do as much diagnosis first while it is in this state, thanks ;).

How are these drives being mounted first?

I mapped them by going to Start - Network, double clicking the server, right clicking the share, and clicking Map Network Drive. I have one folder mapped to U: and one to Z: and neither work. They are both inaccessible at the same time.

Remove them and remap them using the right click on My Computer Method and select Reconnect at Login. this should then allow them to work all the time. Also are the server's setup via static IP?

When I mapped them initially I did select Reconnect at Login, so that probably isn't the problem.
I have removed and remapped them many times in the past to see if that helped, and it did not.

Also are the server's setup via static IP?

Yes, the server is set up with a static IP. It is the Domain Controller as well as where the files live, and I can ping it by netbios name and ip address. That IP is in the client's manual DNS set-up as the preferred DNS also, so I can't fathom why this is happening...

Thanks,

try using the manual command above, and see if it makes any difference.

Also the passwords will not be viewable by anyone else but the Domain Admin and higher.

it would be this:

net use * \\server\ password /user:kara-grief\chris /persistent:yes

If Kara-Grief is the Domain.

Since it cannot find the server can you perform the following

ipconfig /all and post the output?

Tried both of these with the same result:
net use * \\server\ passwd /user:kara-grief\chris /persistent:yes
net use * \\server\ passwd /user:kara-grief/chris /persistent:yes

EDIT: oops. tried the above again with the correct server name, kara-server, but still no luck.
