Email attachment download problem in MailEnable

[eUK-Scott]

Unable to download attachments greater than 4Mb in web mail using Windows 2003

Downloading an attachment shows that the saved file is 0k in size. There may also be an entry in the event log indicating "Response Buffer Limit Exceeded".

CAUSE

IIS6.0/Windows 2003 uses a setting called AspBufferingLimit' to specify the maximum number of bytes allowed in the body of an ASP response. The default for this is 4194304 (4Mb).

RESOLUTION

Instructions for resolving this issue follow:

1. Stop the World Wide Web Publishing Service. This can be done from the Windows Command Prompt as: net stop w3svc
2. In the C:\Windows\System32\Inetsrv directory, find a file called metabase.XML.
3. Copy the original file in Notepad and find the line "AspBufferingLimit".
4. Change the value of this entry to a higher value.
5. Save the file.
6. Start the World Wide Web Publishing Service. This can be done from the Windows Command Prompt as: net start w3svc
