webmethod parameters issue 500 error

    I have 2 web methods in a .asmx file. IIS 5.0, Win2k server.

    The first webmethod takes about 20 string parameters and when I cick
    the invoke button, the pop-up page displays the soap exception that I
    throw for a required field missing. All works fine.

    The second webmethod takes only 2 string parameters. When I click the
    invoke button, the pop-up page shows the http friendly message
    internal server error, 500. The first thing I do is look for the two
    required values and throw an exception if they are not sent, just like
    webmethod #1. There is nothing different happening here. If I go to
    IE tools options adavanced and turn off show friendly http error
    messages, I actually see the soapexception.

    I don't think this will cause a problem when consumed from another
    application, but it does when invoking from the asmx page. Both WMs
    throw the error the same exact way.

    Things i have tried:
    1. Changed the names of hte two webmethods. Worked opposite.
    2. Added the code from WM1 to WM2. Nothing changed.
    3. Added the parameters from WM1 to WM2. This is the kicker! When I
    added the parameters, suddenly WM2 started showing the soap
    exception. So, now it has about 20 string parameters and now it shows
    the soapexception when IE is set to show friendly errors.

    So, i guess I'm not sure if this is an issue of WM1 not showing a
    friendly message or WM2 not showing the soapexception.

    Any ideas or something I can test? Below are both WMs:

    [ WebMethod(Description="Creates a new TP using the following
    parameters:<BR><BR>ORIGUIC: 5 Character UIC [MANDATORY]<BR>ORIGSEQ: 4
