    Here is my setup:

    Have 6 PCs running win98se and 1 PC running winxp pro acting as file server. All are config in same workgroup.

    All the 6 win98se PC are identical in both h/w and s/w setup. Only difference is the Computer Name. Using dynamic IP assigned by router. All have mapped as Network drive a shared folder from the winxp PC.


    Here is the problem:

    Now 1 of the PC will show error during powerup when trying to reconnect to the mapped drive. However if manually go to Network Neighourhood, can see the shared folder and can also access it by clicking on it. After manually accessing it, now clicking on the mapped drive will work too. But once restart system, same thing happen again.

    Changing the Computer Name and problem resolved. However would like to know where in winxp is a particular name banned.

    Note: Change Computer Name and not User name. All win98se login with username "guest" under MS Family Login.


    Thks

    The NetBIOS computer name system has a number of limitations. First is on the number of characters the name can contain, the absolute max being 15, but most admins would recommend 8 - 12 for compatibility with all systems.

    Also there are a few limitations on the characters that you can use in a NetBIOS name. Are you sure that you didn't accidentally give one of the machines a duplicate name?

    What was the exact error message that you were getting?

    Hi Nick,

    Thks for replying.

    The whole network is fully under my control. Computer Name is within the limitation allowed. (The 6 PCs' name are like ABC01, ABC02.......ABC06) Only 1 PC (ABC05) now cannot map the drive. In fact it was working before until recently. Changing the name to ABC15 and it works.

    The error msg is the same like those when the connection is not available, ie "an error has occurs while reconnecting network drive.......".

    Changing back the name to ABC05 and it doesn't work. So look like there is something in winxp that recognise the Name.

    That is weird. If the name is short and doesn't include any dashes underscores dots etc there's no reason why XP should reject it. Are there no differences at all between this PC and all of the others? Are there any other devices on the network that might have been given the computer's name, like a shared printer or similar?

    Try unplugging absolutely every other device from the hub and/or router except the problem PC and the XP PC, and see if it will connect with that name then.

    I have scoured the MS KB and MSDN but haven't come up with anything at all yet that might help.

    Thks Nick for your effort.

    All info provide is correct. Network is pretty simple, ie 6 + 1 PC connected to a 8 port switch and uplink to a Linksys Router. No printer or other devices. All 6 PCs are identical, in fact I just dup all of them after installing the OS, drivers, utilities and applications on 1 PC. Only change is the computer name.

    Have also try swapping to another port on the switch. Release and renew IP. Use static IP. All to no avail except changing name.
