Please Help Me To Resolve The 28017 Error (An Incorrect Or Unsupported HTTP Function Call Was Made), Thanks A Lot.

Now I need to synchonize the data in Pocket PC to the remote sql server database.

I have configured the publication and the virtual directory in the server. When the Pocket PC directly connects to the server (that to say, the Pocket PC connects to the server through the ActiveSync), the data can be synchronized successfully. But when the Pockec PC connects to another computer () through the ActiveSync (this computer connects to the server through the network), the data cannot be synchronized. But when I run the application in the emulator in the same computer, the data can be synchonized with the server.



using the following codes, the error message is:

Error Code: 80004005

Message:

Minor Err: 28017

Source: Microsoft SQL Server 2005 Mobile Edtion.



private void ShowErrors(SqlCeException ex)
{
SqlCeErrorCollection oErrors = ex.Errors;

StringBuilder oStrBld = new StringBuilder();

Exception oInner = ex.InnerException;

foreach (SqlCeError oErr in oErrors)
{
oStrBld.Append("
Error Code: " + oErr.HResult.ToString("X"));
oStrBld.Append("
Message : " + oErr.Message);
oStrBld.Append("
Minor Err.: " + oErr.NativeError);
oStrBld.Append("
Source : " + oErr.Source);

foreach (int iNumPar in oErr.NumericErrorParameters)
{
if (iNumPar != 0)
oStrBld.Append("
Num. Par. : " + iNumPar);
}
foreach (String sErrPar in oErr.ErrorParameters)
{
if (sErrPar != String.Empty)
oStrBld.Append("
Err. Par. : " + sErrPar);
}
MessageBox.Show(oStrBld.ToString(), "SqlCeException");
oStrBld.Remove(0, oStrBld.Length);
}
}


The environment is:

Client:

Sql mobile (sql ce 3.0)



Server:

windows 2003 server

sql server 2000 with sp4

IIS 6



And I'm quite sure the virtual directory is correct.



Any body can help me? It's urget for me, thanks in advance.
