- PROBLEM: 1) A customer was trying to copy a file from the
- workstation to the file server and recieved "Error sending
- on network". He would receive the same error when he would
- do an NPRINT. He could copy files from the file server to
- the workstation with no problem.
-
- 2) A customer had NetWare 386 v3.1 running on a Compaq 386
- SystemPro. The SystemPro had one of Compaq's 32 bit Token-
- Ring adapters in it. The problem was that none of his AT
- machines could copy a binary file to the file server. He
- would get "Network error...". All of his XTs or Micro
- Channel machines worked fine. All of the Token-Ring cards
- were running at 16Mb.
-
- This problem only occurred with binary files.
-
- 3) A customer was running Token-Ring 16/4 adapters and
- NetWare 386 v3.1. When he tried to access any application,
- the workstation would just sit there and the file server's
- "No ECBb Available" count would start incrementing until it
- hit twenty. The workstation would then get "Error receiving
- from network."
-
- 4) A customer upgraded from NetWare 386 v3.0 to v3.1. There
- were no other changes. They had an IBM Model 80 with 8MB of
- RAM, IBM 320MB SCSI drive, and Storage Dimensions 320MB
- drive with a Procomm DCB. They were using a Token-Ring
- topology. After the upgrade workstations would drop off,
- they couldn't create files, and they couldn't invoke
- WordPerfect. Workstations with local hard disks worked,
- although the local hard drive was not being used. They were
- using the new Token-Ring and DCB drivers from NetWire.
-
- SOLUTION: What needs to be done is to set the packet size to the
- maximum. The way to do this is to edit the STARTUP.NCF
- file. Add in a line "set maximum receive packet size =
- 4202". This will make it so that the server will be able to
- receive a packet larger that 1024 (which is the default).
