PRB: Unexpected Network Error 15

ID: Q115699

The information in this article applies to:

Microsoft Delta, version 1.0

SYMPTOMS

Delta displays a series of error messages when you attempt certain commands. The first message box displays the following:

   Unexpected network error 15

Choosing the OK button causes the following message to display:

   Path \\<server name>\...\STAT\<Project Name Directory>\status.mvm
   isn't accessible.

   -or-

   Path \\<server name>\...\<Master Project Directory> isn't accessible.

Choosing OK may cause another error message to display when you are attempting to access an already-created project:

   Can't load the status file for <Project Name Directory>.  Unable to
   verify the status of files in this directory.

These error messages may also appear in the Delta output window.

CAUSE

The lack of a free network drive letter is the primary cause of the "Unexpected network error 15" error message. Performing a command from the Delta GUI requires a minimum of two network drive letters. The first drive letter maintains a permanent connection to the project's master location for the duration of the Delta session. The second drive letter, which is used only temporarily, is mapped to the project's master location while a command is processed and then is discarded when the command is completed.

RESOLUTION

To resolve this problem:

1. Start Delta.

2. Record the letter from the LASTDRIVES statement in the CONFIG.SYS file.

3. Use Windows File Manager, the "net use" command from an MS-DOS prompt,

   or another tool to record the drive letters mapped.

4. If all drive letters allowed in the LASTDRIVES statement are mapped,

   free a drive letter or include additional drive letters in the system's
   LASTDRIVES statement

5. Reboot the system.

6. If drive letters A-Z are mapped, free an appropriate drive letter.

7. Try the Delta command again.

You can use an alternative method if the system requires all network drive letters to be mapped:

1. Temporarily disconnect a network drive to allow files checked in.

2. Check in all files. This updates the local system's changes to the

   project's master location.

3. Using the LEAVE command, remove yourself from the project. The LEAVE

   command removes your local copies of project files.

4. Add the line "SET LOCALDRIVES=X" to the system's AUTOEXEC.BAT file and

   reboot the system. ("X" represents the network drive letter associated
   with the project's master location.)

5. Reconnect the freed network connection and join the Delta project again.

   The JOIN command copies the project files to your local project
   directory.

MORE INFORMATION

The Delta README.TXT file provides additional information concerning the LOCALDRIVES variable.

Other Things To Check

Use the LABEL command to make sure that volume label does not exceed 11 characters, does not contain embedded spaces, and does not contain special characters which are not allowed in MS-DOS names (/, \, &, $, @, and so forth).
Remove any loaded TSRs.
Make sure that there is at least ~430K free conventional memory.
Check the Delta README.TXT to make sure that the network is supported.
