    Connected over a slow link? GPO issue.

    Hi,

    I have one machine that I use for testing/msi creation etc. that regularly gets re-imaged and until now has not had a problem.

    It now refuses to have any software or policies deployed to it via GPO.

    It's been freshly imaged, new ssid applied, joined the domain and happily picks up drive mappings and logon/logoff scripts. I ran gpresult and got the following:

    Now, the bit I'm concerned with is the "Connected over a slow link?: Yes" part. This naturaly stops certain things happening via GPO (software nstallions, redirects etc) but I don't understand why it's reporting this. The machine is new, has a ip reservation allocated and has always worked before.

    I changed the AD settings for Slow Link Detection" to enabled and "0" (effectivly disabling it) but gpresult still shows it at the default of 500. I can ping the server and get a <1ms response. and can copy large files at great speed over the network.

    The machine is now connected directly to the same gigabit switch that the server is plugged into and I even slapped in a new 3com gigabit card to see it was a fault NIC but there was no change.

    Any ideas what to try next? DNS issue perhaps?

    Cheers

    Re: Connected over a slow link? GPO issue.

    This is a symptom of a network connectivity/capacity issue. I suggest you do some network monitoring to see what's going on (an ARP storm caused by a network loop is an obvious culprit).

    The following KB article explains how slow link detection works.

    Thanks, (been to that page ). It's only this one machine that's affected. Some other PCs that have been setup today and yesterday pull the GPO items fine. It still does it when it's the only machine turned on.

    Re: Connected over a slow link? GPO issue.

    maybe the switch port is broken, or theres a cabling problem?

    Forgot to mention that I tried a new cable (tested) and plugged it into different ports and even different switches. I'm going to try the user environment debug mode tomorrow to see if I can extract any useful (read as understandable) info from it.

    Latest drivers installed

    Re: Connected over a slow link? GPO issue.

    we're getting a similar issue with another machine now (a laptop). Doesn't pull any of the GPO settings although gpresult says it does!

    We gave up in the end with the original machine, it just doesn't do group policy! It USED to do it mind, but now... no.

    For the record this laptop indicates that it is NOT connected over a slow link, so the issue must lie elsewhere. I find it particularly odd that some machines fail and the rest are fine.

    I've also noticed that when its installing software every time it whizzes through a list (the software IS installed, but it seems like its attempting to do it again and then give up), thought that was a bit odd too.

    Any ideas?
