Question: I hosted one `DotNetNUke Application` to my production server, and locally it works perfectly. But, when browsing it redirects to the error page. 

How do I set the `default.aspx` as my application default page? I am getting the error as below: 

```
DotNetNuke Error

--------------------------------------------------------------------------------

Windows Vista

 Return to Site 

```

Can anyone can help me, please? Will be appreciated.

**UPDATE:**
Hi, I changed the Path in the PortalAlias table to the server url and `default.aspx` as the starting page, but it displays the `error.aspx` as default page. 

Please help me resolve this problem..

Answer: 
I would try and keep the # of files in each directory to some manageable number. The easiest way to do this is name the subdirectory after the first 2-3 characters of the GUID.
Sorting the audio files into separate subdirectories may slower if `dir_index` is used on the ext3 volume. (dir\_index: "Use hashed b-trees to speed up lookups in large directories.")

This command will set the dir\_index feature: `tune2fs -O dir_index /dev/sda1`
