Hi stullhe104,
Regarding on the "error: 26 .." error you mentioned, based on my research,
it is a error message specific to SQL Server named instance's locating.
Here is a blog article describe this:
#SQL Network Interfaces, error: 26 - Error Locating Server/Instance
Specified
http://blogs.msdn.com/sql_protocols/archive/2007/05/13/sql-network-interface
s-error-26-error-locating-server-instance-specified.aspx
However, as this article mentioned, this is just the direct error message,
the actual cause maybe further dependent. For your scenario, I'd like you
to provide the following information so that I can have a further look
at(in addition to the above article):
1. As you are using the SQL membership provider to store user accoutns
info, correct? if so, are you using a customized membership setting in
web.config and also has your own custom connectionstring? If so, please
paste the configuration section here.
2. After you moved to the production server, whether the SQL Server
instance matches the one one your original server(such as instance name).
If you're using the default "user instance" mode(an attached aspnetdb.mdf
file), you need to make sure user instance is correctly running on the
production server.
You can check the above things in addition to the steps mentioned in the
blog article.
If there is any other findings, welcome to post here.
Sincerely,
Steven Cheng
