No access to internal sites after new Instance of SQL was installed on MS SQL Server
I've got a WSS 3.0 installed on the W2K3 Sever.
Originally, there was only one Instance of MS SQL (MSDE) for Backupexec (bkupexec). Later, we installed WSS 3.0 and instead of installing the new instance of SQL we installed on the same instance (bkupexec). So, at some point all the DBs from Backupexec and DBs from WSS were all together within the same SQL instance.
After we noticed this we wanted to split those two into two separate instances: bcupexec and sharepoint. First, I have done a backup of all DBs within backupexec instance. Then, I installed new SQL Instance and called it Sharepoint and tried to restore all WSS DBs into the new SQL instance. Once that was done I check references in IIS so Content and Config would point into the new instance. But since then no go.
I can access Admin site from within IIS and from the browser. I cannot access any internal WSS sites. It asks for the authentication. All I am using is Windows authentication. Account is in AD.
As I am new to WSS I will be greateful for all suggestions and possible fixes.
