Let me suppose you are using Windows XP.
The remote computer must be on line, on the local network, when you turn on your computer. If not, the drive map will fail.

How to connect and disconnect a network drive in Windows XPNote Network drives are mapped by using letters starting from the letter Z. This is the default drive letter for the first mapped drive you create. However, you can select another letter if you want to use a letter other than Z.
Please notice that this article does not suggest that you need to use a different method if the drive map fails. Nor does it suggest that using a different drive letter will solve the problem. There is no apparent reason to use a drive letter other than just the letters eating, which is the default letter or a mapped drive. whenever a network drive fails to connect, you can use this procedure as follows.
Go into my network places, locate the area where you can dismount or disconnect any network drive. After doing a disconnect of the drive, see if you are able to locate that particular shared folder again in network places. If it is not available on the network, you're not going to be able to map it to a drive letter. You may have to use the find feature to find remote computer on the network.
In other words, if the computer and its shared folders are not visible on the network, the drive mapped is bound to fail.
Once you have located the resource again, you should have no trouble doing the drive map.
That is about as much as I can say. Using different methods map the drive is not the way to solve the problem. All of the methods work. Or they all do not work. If network places cannot find the resource on the network, the map will fail.
