Microsoft Windows Server 2003 Enterprise Edition
PXE Server leaves ports 524 and 998 open which eventually causes RPC failures
PXE Transaction Server leaves ports 524 and 998 in a "Close_wait" state which eventually uses up all available RPC connections
PXE Server causes networking on a Windows Server to fail due to a large number of open ports
Caused by a very unique combination of services running on several servers throughout the tree, which in turn didn't close connections on 524 and 998 to the PXE Transaction Server.
Workaround - Stop and restart two PXE Windows services, namely, "ZENworks PreBoot Transaction Server" and "ZENworks Preboot RPC Port Mapper".
Fixed in two ZENworks Imaging Server files, ZENPXE.DLL Dated 10 August 2004 or in zfd65u2.exe or newer, and ZENIMGDS.DLML Dated 12 August 2004 or in zfd65u2.exe or newer newer found at Novell Support
