fix

This is a known Microsoft Defect.

Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Novell cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys and Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT or Windows 2000, you should also update your Emergency Repair Disk (ERD).

The default maximum number of ephemeral TCP ports for Microsoft Windows NT is 5000. A new parameter has been added to Windows NT 3.51 Service Pack 5 and to Windows NT 4.0 or higher. To increase the maximum number of ephemeral ports you must set the following registry parameter:

Start Registry Editor (Regedt32.exe).

Locate the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Paramete rs

On the Edit menu, click Add Value, and then add the following registry value:
Value Name: MaxUserPort Data Type: REG_DWORD Value: 65534 <for example&g t;

Valid Range: 5000-65534 (decimal) Default: 0x1388 (5000 decimal)

Description: This parameter controls the maximum port number used when an application requests any available user port from the system. Normally, ephemeral (that is, short-lived) ports are allocated between the values of 1024 and 5000 inclusive.

Quit Registry Editor.
