Environment


Novell NetWare 6.5 Support Pack 8
Novell NetWare 6.5 Support Pack 7

Situation

Huge delays accessing files over NCP
Drive letters are mapped double clicking a drive letter results in the files in those drive mappings to not display
Re-authenticate, re-login, disconnect the drive and re-map the drive again sometimes allows file access again

Resolution

Set the "Minimum NCP TCP receive window to advertise" on the server back to the default value of 4096.
