Mapped Drives not Connecting

Did you move to Canberra recently? My commiserations

It would be useful to figure out whether the Win7 box is trying to reconnect and failing, or whether it's not trying at all. The most direct way to do that would be to run a packet trace (www.wireshark.org) on the XP target (harder to do it on Win7 while it's logging on), and then analyse the resultant trace to establish whether an attempt is being made to reconnect.

If the Win7 box is trying and failing, that's relatively easy to troubleshoot because the trace should reveal the nature of the failure. Otherwise, if there's no attempt at all, it becomes necessary to enable additional ("userenv") logging, and as of Vista they've made that a real PITA.

If you do end up generating a trace (it's very simple - like a tape recorder) and you'd like some assistance doing the analysis, just ask.

Did you solve this?
I found the same in vista and XP, Ticking the "reconnect at startup" dosen't work. The best way is to go to control panel, hover the cursor over the "family security" section, all the options will be highlighted by a box, click in the box area but not on any specific section. You can now setup credentials for each mapped drive, this involves selecting each drive inturn from a list and applying your login password. This will ensure that all drives will be connected at bootup. I've noticed that sometimes the dirves can still have a red cross on startup, but is actual connected just select as normal and the redcross disappears.
Ps I've written this from memory so I'll post again later this evening to correct any errors..the jist of it is close

Did you manage to do it.
