SYMPTOMS

[*]Nothing occurs.
[*]The new window may be blank.
[*]You may receive a scripting error message that is similar to the following error message:No such interface supported.
[*]Internet Explorer may not respond when you click Print or Print Preview in the File menu.
When you try to connect to Web folders, you may receive the following error message:The current operation could not be completed because an unexpected error has occurred.
CAUSE
This behavior may occur for one or more of the following reasons:
[*]The (Default) value setting in one or more of the following registry keys points to an incorrect location for the Urlmon.dll file:
[HKEY_CLASSES_ROOT\CLSID\{79eac9e0-baf9-11ce-8c82-00aa004ba90b}\InprocServer32]
[HKEY_CLASSES_ROOT\CLSID\{79eac9f1-baf9-11ce-8c82-00aa004ba90b}\InprocServer32]
[HKEY_CLASSES_ROOT\CLSID\{79eac9f2-baf9-11ce-8c82-00aa004ba90b}\InprocServer32]
This Behavior May Occur if you install a customized version of Internet Explorer that was created with the Internet Explorer Administration Kit (IEAK) version 5.01 Service Pack 1 (SP1), 5.5 SP1, or 6.0.
[*]The following registry key is missing or damaged:
HKLM\SOFTWARE\Classes\Interface\{00020400-0000-0000-C000-000000000046}
[*]One or more of the following files is missing, damaged, or improperly registered:
Urlmon.dll
Mshtml.dll
Actxprxy.dll
Oleaut32.dll
Shell32.dll
Shdocvw.dll
RESOLUTION
To resolve this problem in Internet Explorer, follow these steps:
1. Quit all programs that are running.
2. Click Start, and then click Run.
3. Type regsvr32 urlmon.dll, and then click OK.
4. When you receive the "DllRegisterServer in urlmon.dll succeeded" message, click OK.
If this does not resolve the problem, repeat steps 2 through 4 for each of the following files (in step 3, replace Urlmon.dll with each of the file names below):
Shdocvw.dll
Msjava.dll
Actxprxy.dll
Oleaut32.dll
Mshtml.dll
Browseui.dll
Shell32.dll (Windows XP and Windows 2000 only)
If the problem is still not resolved, verify that the following registry values are present and correct:
HKLM\SOFTWARE\Classes\Interface\{00020400-0000-0000-C000-000000000046}
Name: (Default)
Value: IDispatch
HKLM\SOFTWARE\Classes\Interface\{00020400-0000-0000-C000-000000000046}\ProxyStubClsid
Name: (Default)
Value: {00020420-0000-0000-C000-000000000046}
HKLM\SOFTWARE\Classes\Interface\{00020400-0000-0000-C000-000000000046}\ProxyStubClsid32
Name: (Default)
Value: {00020420-0000-0000-C000-000000000046}
If the problem is still not resolved, reinstall Internet Explorer. If you are using the version of Internet Explorer that is included with your operating system, reinstall or repair your operating system.
