Q193521
The information in this article applies to:
-
Microsoft Windows NT Server NetShow Services version 3.0
IMPORTANT: This article contains information about editing the registry.
Before you edit the registry, make sure you understand how to restore it
if a problem occurs. For information about how to do this, view the
"Restoring the Registry" Help topic in Regedit.exe or the "Restoring a
Registry Key" Help topic in Regedt32.exe.
SYMPTOMS
When you configure a Broadcast Publishing Point for HTTP distribution
streaming using a URL that indicates a port other than 80, you may receive
the following error message:
A remote station URL must begin with 'MSBd://' or 'HTTP://'
WORKAROUND
You must use Port 80 when doing HTTP distribution. By default, Windows NT
Server NetShow Services uses port 80 when it performs HTTP distribution.
This behavior can be changed in the registry.
The port that NetShow Services uses for HTTP distribution is stored in the
following registry key.
HKey_Local_Machine\System\CurrentControlSet\Services
\nsunicast\Parameters\HTTPPort
By default, this value is set to 0x50 (or 80 in decimal) and under normal
circumstances should not be changed. Use the following steps to change
this value back to its default of 80.
WARNING: Using Registry Editor incorrectly can cause serious problems that
may require you to reinstall your operating system. Microsoft 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, you should also update your Emergency
Repair Disk (ERD).
To change the port that NetShow Services uses for HTTP streaming, perform
the following steps:
- Start Registry Editor (Regedt32.exe).
- Locate the following key in the registry:
HKey_Local_Machine\System\CurrentControlSet\Services\nsunicast\Parameters
- In the key listed above, locate and double-click on the value named
"HTTPport." This should open the DWORD editor.
- Click the Radio button labeled "Decimal" and enter 80. Click OK.
- Restart Windows NT Server.
STATUS

3.0 Services.
