To use The Brainex Door Manager on a network, each node should have in it's DOS path the Brainex directory. This is where BRAINEX.DAT is located. Usually this is C:\BRAINEX. The Brainex directory must be located in the root of the drive. Each node should also have the SET BRAINEX=C:\BRAINEX\BRAINEX.INI statement. The drive letter will vary depending on the drive you specify when installing Brainex. Check each node by typing SET from the DOS command line. You should see the SET commands and path. If you get errors indicating files can't be found, or Brainex doors can't find files, it's usually due to improper set and path statements.
