Windows 7 cross-forest connectivity

Hello,

I'm having a strange issue where I have created a sysprep Ghost image of a windows 7 installation in my Seattle office. I copied it down to the LA office to let the IT team start rolling it out. The first machine they got up joined the LA domain fine and can connect to all shares and servers, but when they try to connect to our Seattle severs via UNC path they get an error that the path was not found.

I try pinging the workstation with the firewall off and i see DNS resolving the name but no replys come back.

The build is windows 7 enterprise. I am currently using here in Seattle with no problems connecting to LA. very strange.

thanks!
Frank

Hi,

are the folks in Seattle using \\server\share or \server.domain.com\share for their UNC path? NetBIOS over TCP/IP may not be on.

As Firebar has pointed, this error "network path not found|" has been fixed on windows7 by enabling netbios over tcpip.

I have attached a screenshot as well.

Will keep checking back here.

The NBT/IP settings are designed to be inherited from the DHCP server. If DHCP is not set to hand that information out, the client will resort to broadcast, which does not go across routed interfaces.

Hi Firebar and Mutahir,

I believe Seattle uses \server.domain.com\share for their shares across offices.

I have asked that this setting be enabled and it is. I am still unable to ping the machine nor VNC into it.
Very strange, the user cannot access our server still via VNC path.
Am i verifying if the DHCP server (cisco 4807) is supposed to be supplying DNS and WINS?

thanks!

WINS would have to be proxied across subnets, but I could be off on that statement.

Are the File and printer sharing ports (137-139, 445)open on these routers? I would guess they are, given your statements in the question.

I'm thinking maybe it could be the SSIDs were not stripped off completely from the machine when it went into sysprep. If i bring a machine up here from the image it is still showing our domain in the workgroup field. Like i mentioned earlier, when i issue out the image here in Seattle the systems have no trouble accessing either offices' resources. But i'm not sure why the image would only let the LA server resources be available.

My boss also has his own install of Windows7 , let me see if he can hit our shares from there.

thanks,
Frank

SSID's? Are wireless networks involved. Windows Vista/7 categorize network connections according to one of three types; Home, Work, Public. The security of each ranges from low to high depending on which type is selected when the network is detected by Windows and NLA. If you have a wireless LAN, categorized as 'Public' file and printer sharing will not be available.

scratch that extra "S" I meant security identifiers

as a test , you can deploy the same image and sysprep at the remote location and re-join the domain and see if that comes through to your seatle office.

Also, before attempting sysprep, try to access the shares in seatle via ip address ?

Breaking news on this,
it turns out my Check Point VPN client was interfering with the connectivity to the remote offces. With the Check Point box checked it was not responding to pings nor hitting server shares.

i've built the CIsco VPN client and Check Point client into my image. I will  make sure to look for this in the future.

thanks for both your help on this.

Glad you have figured out - we would have suspected any vpn clients too but we both didn't knew :-)

Watchguard vpn client has given me a lot of problems lately too :-)

Have a good day ahead
