Sometimes you might notice problems opening the Network connections. For example all connections have disappeared, or when you create an Internet connection you might find the options Network Connection Dial Up Modem and broadband connection with user name and password are grayed out.
In order to troubleshoot this you have first to check if the service Remote Access Connection Manager is enabled, so do the following these steps:

1. Open Control panel -> Administrative Tools -> Services
2. Scroll down to Remote Access Connection Manager anche check if it's enabled
3. If it's not enabled, double click it and then click Start

If you got the error message Error 126: specified module could not be found when starting the service, do the follwing steps:

1. Click Start and then Run...
2. Type cmd and press Enter
3. Type regsvr32 netshell.dll and press Enter
4. Type regsvr32 netcfgx.dll and press Enter
5. Type regsvr32 netman.dll and press Enter

If you get the error message specified module could not be found for any of those commands, those files might be missing from the \Windows\System32 directory. Just copy those files from another PC having the same operating system, or restore them from the XP Setup CD doing the following steps:

1. Insert the Windows XP Setup CD in the CD player
2. Click Start, type cmd and press Enter
3. In the General tab click Expand file...
4. In the File to restore box enter the filename you want to expand, i.e. netcfgx.dll
5. In the Restore from box enter the path of the compressed file in the Setup CD, i.e. H:\i386\netcfgx.dl_ (or just click Browse and search for the file in the CD)
6. In the Save file to box enter C:\Windows\System32 (assuming C: is the drive where Windows XP is installed)
7. Click Expand

Now you can redo the regsvr32 commands for the expanded files, and then try to enabled the Remote Access Connection Manager service. When enabled, you will be able to browse the Netword connections page and create all kind of connections.
