I have recently encountered a problem with being unable to open the
management console. I have found the knowledge base article that I
suspect relates to the issue but its resolution is meaningless to me.
Here is the message:

SYMPTOMS
If you try to check the permissions in the Web storage system, when you
click the Security tab, you may receive an unspecified 0x80004005 error
message.
Also, when you start the SharePoint Portal Server Administrator console,
you may receive the following error message:
Unable to open the SharePoint portal server named " server_name"

CAUSE
This issue may occur if the Msdmisap.dll file is missing in the
application mappings. These mappings are located in the Internet
Information Services (IIS) Administrator. To locate the mappings, click
the default Web site, right-click click SharePoint Portal Server, and
then click Properties. Click Virtual Directory, and then click
Configuration.

RESOLUTION
To resolve this issue, use Metaedit to add the Msdmisap.dll file mapping
manually:
Expand LM, expand w3svc, and then expend the 1 folder.
Click the root, click SharePoint Portal Server, and then click
scriptMaps.
Add the following entry:
*,C:\program files\Sharepoint Portal Server\bin\Msdmisap.dll,1

Problem is that I have not used Metaedit and have little idea what the
LM reference is.

Has anyone encountered or resolved this issue?
