Summary:
The following two sections describe the problems corrected by the
patches to LAN Manager version 2.00b. Patches 4 and 5 correspond to
the LAN Manager 2.00 CSD levels. The CSD level can be verified by
checking the content of the LANMAN.CSD file (located in the LANMAN
directory). The following is a list of the CSD levels for LAN Manager
2.00:
CSD 1 is LAN Manager 2.00a.
CSD 2 is LAN Manager 2.00b.
CSD 3 is LAN Manager 2.00b for MP.
CSD 4 is the first patch to LAN Manager 2.00b (patch 4).
CSD 5 is the second patch to LAN Manager 2.00b (patch 5).
These corrections are cumulative. As a result, patch 5 contains all
the bug corrections from patch 4 as well as patch 5.
Section 1: Problems Corrected by Patch 4
----------------------------------------
This section describes the problems that were corrected for the Patch
4 update to LAN Manager 2.00b.
TITLE
Deadlock in MSPBEUI Under Stress with UP MAC Driver
DESCRIPTION
Under stress from one client (two sessions of test to 100 MB file
and one named pipe session), MSPBEUI would hang with the first
processor stuck with the interrupts off.
TITLE
Named-Pipe Semaphore Fails to Clear
DESCRIPTION
When messages written to a named pipe are much larger than the
SIZWORKBUF and SIZREQBUF parameters, the server will fail to clear
the semaphore associated with a named pipe when data arrives. It
will also lock the client workstation.
TITLE
Used Resources Grayed Out on Server in nif
DESCRIPTION
When you set the focus to another server in the NET nif, the used
resources are grayed. Therefore, the user is unable to use any
resources. This happens only when you are on a machine with its own
NET.ACC file and you don't have an account in this local NET.ACC
file (you have guest privileges locally).
Section 2: Problems Corrected by Patch 5
----------------------------------------
This section describes the problems that were corrected for the
Patch 5 update to LAN Manager 2.00b.
TITLE
DOS Tree on Net Drives
DESCRIPTION
Under DOS, on remote drives, Tree recursed down the first branch of
the tree and then terminated. The problem was the inability of LAN
Manager (2.00b) to recycle DOS file search handles if it ran out of
them. They would only be recycled after the 10 minute expiration
time had passed.
TITLE
Stack Switching Code Broken in DOS Messenger
DESCRIPTION
If you're in the messenger and you get another interrupt for the
messenger, the messenger will switch stacks. The common example of
this is getting a message larger than 128 characters in size.
TITLE
Trap 00D When Sending Messages of Various Sizes Across a Pipe
DESCRIPTION
When sending messages of various sizes from a client to a server
across a single direction pipe, the server will Trap00D in ring 0.
TITLE
Two Server Side Writes Do Not Work Correctly
DESCRIPTION
On a nonblocking byte mode pipe, attempt two server side writes of
size greater than the pipe buffer size with no client side reads.
The first write is correctly truncated to the pipe buffer size, but
the second write is blocked until a write arrives. The second write
should not block, but return immediately with 0 bytes written.
TITLE
Incompatibility Between Netpopup and Graphics Mode Applications
DESCRIPTION
Getting a popup while in graphics mode in applications such as
Works or Word, then clearing it, causes the palette to be changed.
TITLE
Sending 55,000 Byte Message Across Many Clients Will Trap 000D
DESCRIPTION
Using named pipes, opening roughly 14 clients sending 55,000 byte
messages to a server will cause the server to Trap 000D.
TITLE
Accessing the Same File Using Edlin from DOS Clients Fails
DESCRIPTION
Using Edlin from DOS clients to open the same remote file at the
same time will not work correctly if the partition is FAT and the
srvheuristic 11 bit is set to 3.
TITLE
Local Security Doesn't Seem to Work Correctly on LAN Manager 2.00b
DESCRIPTION
You cannot successfully start the workstation under local security
using LAN Manager 2.00b and OS/2 1.30. The NET START WKSTA command
(or NET START SERVER) from PRIVINIT.CMD will print out "."
infinitely.
TITLE
NETWKSTA.EXE Nmpipe (4087 Byte Msgmode) Read Hang in Windows 3.00
DESCRIPTION
The Saros FileShare Windows application, when running in Windows
3.00 in 386 Enhanced mode with the LAN Manager 2.00 WINNET driver,
is transferring files from server to client via blocking,
message-stream named pipes. If the total message size is 4087
bytes -- for example, the file to transfer is 3457 bytes and the
Saros message packet overhead is 630 bytes -- when the client
application calls read to get the data from the server, control
never returns to the application. This failure occurs only when
running in enhanced mode Windows, not real or standard mode
Windows.
