Slow administrative shares

[dslam24]

I have a very odd problem. There is an administrative share that I need to access.

\\server\share$

When I go to start> Run and type in the share, it takes about 35 seconds to open. It has been doing this for a long time over a year, it doesnt happen on every machine, only a few, Vista SP1 and XP SP3.

Just recently I discovered that if I open up File explorer and try to access the share from there, it opens immediately.

I've done some traffic captures to see what's going on when it's taking for ever, here is the two errors I get.
I think the first one is fairly normal.
SMB Trans2 Response, GET_DFS_REFERRAL, Error: STATUS_NO_SUCH_DEVICE

I think this one is the problem, however the share is there, it opens it after a bit.
SMB Tree Connect AndX Response, Error: STATUS_BAD_NETWORK_NAME

It disconnects about 15 seconds into the request, and then it tries again at about another 15 seconds, then the folders open up.

Any Ideas?

Not much on Google about that error message, one or two there mention Samba, Do you have that at your office?

Do you see the same hang if you try connecting one of the machines while it is loaded in "Safe Mode with Networking"?

If not, then check if anything else is slowing it down.

what happens when you create a LINK to the share?

or try this:

Create a shortcut to explorer.exe and pass the UNC name of the resource.
explorer /e, \\Server\FileShare

how about mapping the share instead?

it could be the Link-Layer Topology Discovery Responder that is causing havoc there. It tends not to play well with older network equipment...

also I found that IPv6 gets in the way of things, so uninstalling it from the properties of the NICs in question (XP only, VISTA read below)...

have a peek:
