CONF: Hotsite: TCP/IP Fails with Error PR00022 During Boot

ID: Q112580

The information in this article applies to:

Microsoft LAN Manager, version 2.2b

SYMPTOMS

On boot, a LAN Manager 2.2b OS/2 server fails with this error:

PRO0022: UNSPECIFIED FAILURE in binding CLIENT to TCPIP_XIF

CAUSE

An OS/2 server running TCP/IP may fail if it is accessed by another client during the boot process, because the server's TCP/IP stack is too busy dealing with numerous SYNs from the client to bind.

RESOLUTION

A fix to this problem is in development, but it has not been regression tested and may be destabilizing in production environments. Microsoft does not recommend implementing this fix at this time. Contact Microsoft Product Support Services for information on availability.

STEPS TO REPRODUCE BEHAVIOR

Set up a TCP/IP-only server with LAN Manager 2.2b

Have six or more other machines execute this command in a loop:
```
      net use v: \\server\share ; net use v: /d 
```

Reboot the OS/2 server.

A trace looks like this:

workstation --(SYN)-----> server

workstation --(SYN)-----> server

workstation --(SYN)-----> server

server -------(ARP)------> Broadcast

workstation---(SYN)-----> server

server--------(ARP)------> Broadcast

workstation---(ARP REPLY)> server

server--------(RESET ACK)> workstation

In a good trace, frame #8 is a SYN ACK rather than a RESET ACK.
