* package can be distributed to any one who has a license for
* this product.

*
*
* PRE-REQUISITES
* --------------
* IBM Communications Server for Windows, Version 6.1.2
* FixPack 2 (JR20883)
*
* This fix is designed for use with FixPack 2 of CS/Windows V612.
* It is not designed for use with any other level of the product
* and may cause irreparable damage if inappropriately applied.
*
* No other prerequisites are required for the installation of 
* this fix.
*
*
* APAR DESCRIPTION
* ----------------
* EEDLC source ports changed to use 12000-12004 vs first available
* 
* ERROR DESCRIPTION
* -----------------
* EEDLC uses the first available ports, instead of ports 12000
* through 12004, for the source UDP ports.
*
* PROBLEM SUMMARY
* ---------------
*   USERS AFFECTED: All who use EEDLC (Enterprise Extender).
*
*   PROBLEM DESCRIPTION:
*   The use of the first available (apparently random) source ports
*   can cause difficulty with firewall configuration, including 
*   the firewalls of Windows XP SP2 and Windows 2003 SP1. This can 
*   cause link activation problems.
*
*   PROBLEM SUMMARY:
*   Architecture design is to use ports 12000-12004 as both the
*   source and destination ports for an EEDLC link. This is 
*   consistent with other EEDLC products.
*
* PROBLEM CONCLUSION
* ------------------
* The EEDLC code was changed to use port 12000 for the source
* port for all EEDLC traffic from CS/Windows. A future update
* is planned to include a design change to have EEDLC use source
* ports 12000-12004 based on SNA network priority as EEDLC 
* architecture defines.
*
*
* This apar includes all current and previous apar maintenance
* against the CS/Windows V612 Enterprise Extender DLC or EEDLC
* component since the GA of the product through April 14, 2005.

* INSTALLATION INSTRUCTIONS
* -------------------------
*
* The PARTS LIST is as follows:
*
* FILE          SIZE    DATE        DESTINATION
* pdlndldl.sys  69,632  04/14/2005  \WINNT\SYSTEM32\DRIVERS  or
*                                   \WINDOWS\SYSTEM32\DRIVERS
*
* Installing the fix:
*
* 1) Be SURE you have downloaded JR21316_6122.ZIP in BINARY format.
*
* 2) Create a temporary directory and extract the files in 
*    JR21316_6122.ZIP into the directory.
*
* 3a) Stop Communications Server for Windows NT (including the node,
*     Node Operations, Node Configuration, Log Viewer, and any other
*     CS/Windows components that are running).  Note that there may 
*     still be CS/Windows-related services running on the machine 
*     after stopping these applications, but this is normal and 
*     should not affect the installation of this fix package, with 
*     the exception of the two modules listed in the next step.
*
* 3b) Right click on the Windows bar and select Task Manager. Under
*     "Processes" select RAPISERVER.EXE and end the process. Select
*     PCS_AGENT.EXE and end the process, then close Task Manager.
*
* 3c) Stop the EEDLC service:
*     net stop ldlcserv
*
* 4a) Rename the original file:
*     C:
*     cd \WINNT\SYSTEM32\DRIVERS
*     ren pdlndldl.sys pdlndldl.sys_preJR21316
*
* 4b) Copy the new file into place:
*     cp (path)\pdlndldl.sys C:\WINNT\SYSTEM32\DRIVERS\pdlndldl.sys
*
*     (replace WINNT with WINDOWS as appropriate, such as for a 
*      Windows XP system)
*
* 5). Shutdown and Restart WINDOWS to reboot the machine.
*
* 6). You can now start CS/Windows Node Operations and the node.
