APPLIES TO

- Microsoft Windows for Workgroups 3.11

This article was previously published under Q123095

## SYMPTOMS

The following error message may occur when you start Windows for Workgroups version 3.11:
Invalid VxD dynamic link call to device # 0484, service 800D. Your Windows configuration is invalid. Run the Windows Setup program again to correct this problem.
After receiving this message, you cannot enter Windows.

## CAUSE

This error message is caused by either a corrupted IFSMGR.386 file, or a missing device line in the [386Enh] section of the SYSTEM.INI file.

## RESOLUTION

To correct this error, verify that the device line exists in the SYSTEM.INI file. If necessary, edit the SYSTEM.INI file with a text editor, such as Windows Notepad or MS-DOS Editor, and add the following line to the [386Enh] section:

device=ifsmgr.386

Then, expand the file from your original Windows for Workgroups 3.11 disk set to your Windows SYSTEM subdirectory. For example, if your hard disk is drive C and your Windows directory is called WINDOWS, type the following command:

c:\windows\expand a:\ifsmgr.38_ c:\windows\system\ifsmgr.386

NOTE: The file IFSMGR.38_ is located on Disk 4 of the 3.5-inch disk set and Disk 5 of the 5.25-inch disk set.
For more information about using the EXPAND command, type "EXPAND /?" (without the quotation marks) at an MS-DOS command prompt.
