When converting an application from Net Express 3.1 to a later release of Net Express, running the application under Server fror COBOL results in the following error message being displayed:

"Procedure entry point mF_PALETTE could not be located in the dll cblrtss.dll"

The mf_palette entry point was something that was present in Net Express 3.1 but not in later product releases.

It sounds as if one or more of your application files did not compile successfully in the newer Net Express version so the 3.1 version is being picked up incorrectly.

Try the following:

1.  Check the timestamp of the executable files in the application and make note of any that have an older timestamp than you expect.
2.  Make sure that the PATH and COBDIR environment variables do not reference a location that contains an older 3.1 compiled version of any of the application files or the Net Express run-time files.
3.  The Net Express IDE Find in Files command can also be used to search for all files in a prticular directory structure that contain the text mf_palette. This will report a list of files containing this string.
Any files reported are most likely 3.1 files and need to be replaced by the newer ones.
