Under Windows Server 2008 I'm unable to run many utilities that use network resources. This works just fine under Windows Server 2003.

For example:

  • \\domain\dfs\tools$\bin\sendmail.exe ...
  • \\domain\dfs\tools$\bin\psexec.exe ...
  • echo %_metric% %_value% %_unixtime% | \\domain\dfs\bin\foo$\nc graphite.domain 2003 -w1

Reproducing and maintaining this folder on a large number of servers/vm's is not desirable. Is there a way to allow Windows Server 2008 to run these tools? If so, can this be enabled via GPO or in a fashion that can be scripted during automated builds?

Edit: The commands/tools do work just fine, when run from local drives.

Edit2: Wget example:

d:\scripts\helpers>z:\bin\wget http://www.google.com SYSTEM_WGETRC = c:/progra~1/wget/etc/wgetrc syswgetrc = z:/etc/wgetrc --2011-04-11 00:32:15-- http://www.google.com/ Resolving www.google.com... failed: Host not found. z:\bin\wget: unable to resolve host address `www.google.com'

wget can neither use DNS to resolve the IP nor can it use HTTP if provided an IP directly.

Edit3: The problem seems to be tied to DFS/DFS shares. Tools run correctly from other normal windows-server file-shares. They also run correctly when run directly from the file-servers behind the DFS. They only fail when we attempt to run them from the DFS UNC path or mapped drives.

I was facing the same problem but it was resolved when I disabled access-based enumeration for this namespace.

You may want to try the same.

Add the remote share into IE's Trusted sites zone.

  • Tried that. Added *.domain to local intranet, also tried trusted sites and with explicit server names. Same results, exe runs, but can't open sockets/network resources. DEP disabled, UAC disabled, domain,public, private firewall policies disabled. Tools are on a DFS, tried to hit the file-servers behind that directly also. No luck. Commented Apr 10, 2011 at 8:21
  • Try adding it in UNC format \\server\share Commented Apr 10, 2011 at 9:21
  • Tried UNC file:////\\server\share as well as a few other variants. Still no go. Commented Apr 11, 2011 at 5:34
  • If you map a drive to the share, do the programs run? Commented Apr 11, 2011 at 5:47
  • The programs run, but again something is blocking outbound connectivity. Wget runs, but is unable to connect out to do DNS lookups or HTTP calls. Commented Apr 12, 2011 at 2:20
