Release Notes for the Cisco Building Broadband Service Manager 5.1 WEBpatch Patch
January 2002
These release notes describe the Cisco Building Broadband Service Manager (BBSM) 5.1 WEBpatch patch (WEBpatch51SP1.exe), also known as patch 1044.
CautionYou must install this patch on the BBSM Server before you install BBSM 5.1 Service Pack 2 (SP2).

Patch Details
The following information and resolved caveats are included in WEBpatch51SP1.exe, the WEBpatch patch. This patch applies only to Cisco Building Broadband Service Manager 5.1.
CSCdv63477
Synopsis
SP1 includes a new version of atnat, which is a Windows 2000 NDIS intermediate driver that is installed between the internal NIC and the TCP/IP stack on the BBSM Server and provides BBSM's plug-and-play capabilities. After WEBpatch installed SP1 and rebooted, the new atnat was installed in c:\winnt\system32\drivers. However, the program was not actually loaded and running in Windows 2000. It was necessary to reboot the server a second time to get the new atnat loaded and running.
Cause
During the BBSM 5.1 installation, the c:\winnt\system32\drivers\atnat.sys was installed as a read-only (RO) file. During the SP1 installation, WEBpatch would determine that atnat.sys was read-only and created a deferred copy of the new atnat.sys. After that, WEBpatch finished the installation and then rebooted.
During the reboot, Windows 2000 would request the deferred copy of the new atnat.sys, but it would load atnat very early in the startup sequence before any deferred copy operations could be carried out. Consequently, Windows 2000 would load the old atnat before copying the new atnat over the old one. A second reboot was required to correctly load the new atnat program.
Resolution
WEBpatch now removes read-only protection from c:\winnt\system32\drivers\atnat.sys, copies the new atnat over the old atnat, and reboots. After WEBpatch reboots, atnat is correctly loaded and running.

Synopsis
The WEBpatch PNF file specifies which files to update on the target server. If one of these files was in use by ISA, the patch upgrade failed.
Cause
This is a Microsoft issue. An access violation occurred when CFile::SetStatus() attempted to remove the RO flag of a shared ISA file that WEBpatch tried to upgrade.
Resolution
The attrib -r command now replaces the CFile::SetStatus() to remove the RO file status.

Synopsis
WEBpatch supports a hotfix feature that allows customized files to be executed during patch installation. This feature should have supported executables (exe), command files (cmd, bat) and other script files (vbs). However, the feature would fail if the patch contained or specified a hotfix that was not an executable file. An installation not successful warning would appear. Debug log entries for the patch install would also show a PatchUtil::StartCmd error entry.
Cause
In BBSM 5.1, the system method for invoking hotfix files through the command interpreter was replaced with CreateProcess(), which provides more details if errors occur during the process being invoked. However, the CreateProcess method only supports executable files.
Resolution
WEBpatch has been modified to use the system() method if the command being executed is not an .exe file. The CreateProcess method is still used to support executable files.
Installation
Use the WEBpatch option in BBSM to install this patch.
