    Re: randomly falling off domain

    We had a room which had machines doing that last term, during the summer we re-terminated the network points and its been fine ever since. Even though when we took the socket off the wiring looked ok, we still re-patched the points anyway

    Re: randomly falling off domain

    Have you tried generating new SIDs for the computers concerned? Just a thought, I've heard of all sorts happening in a local high school (not mine) where the tech was imaging but not using sysprep to regen the SID.

    Worth a try, other than that I'd go with Jake's idea!

    Re: randomly falling off domain

    Is it the same 4 every time?
    What do you mean by falling off, are you having to manually re-create their accounts on the domain?

    on the workstation putting it in a workgroup and then back on the domain fixes it.

    what would be possible reason for this.I am having the same issues.

    Falling of means account is deleted from domain,i guess

    DHCP scope full?
    If they've been imaged but not sysprepped (as below) Try regenerating the SIDs
    Faulty wiring or wireless problems?
    Faulty NICs?
    I had an issue earlier this term with reserving IP addresses in a range where the leases were already out, a load of the teachers laptops wouldn't see the domain, resolved by moving the lease range to not encompass the reserved range (now why didn't I do that in the first place...)

    most of the falling of coincided with user changing pword
