After DCOM configures the excel permission, ASP. NET fails to generate an excel file (the exception is HRESULT: 0x800A03EC ),

I found a lot of information on the network speed and did not solve it effectively. Finally, I changed the "SaveAs" method to "SaveCopyAs.

 

For example:

 

'Workbook. SaveAs (Server. MapPath (".../../DownLoadFile/" + newFileName) 'is saved first

Workbook. SaveCopyAs (Server. MapPath (".../../DownLoadFile/" + newFileName ))

...

The 'workbook. Save () 'operation is complete and then saved.

Workbook. SaveCopyAs (Server. MapPath (".../../DownLoadFile/" + newFileName ))
