After reinstalling Windows Server 2008 R2 EE my SQL 2008 R2 Sp2 Instances have some connection issues.
The server were installed under the same hostname, but he got a new sid in my active directory.
On the server there one DB Engine MSSQLSERVER, two named Reporting Services for MS crm 4.0 and SCOM and one Analysis Services Instance.
The DB Engine will collect Data from another DB, before writing to Analysis Services.
Here are the problems on the server:
- When I connect via SSMS remotly, I sometimes get this error: Failed to connect to server <hostname> ... Named Pipes Provider, error 40 - Could not open a connection to SQL Server - Error 5
- Both RS Instances have many event log errors like "Report Server (Instance) cannot connect to the report server database.". RS Reports are working fine, but sometimes the rendering is taking a long time.
- The DB Engine Agent Job to collect Data sometimes throw the following error: An OLE DB error has occurred. Error code: 0x80004005. An OLE DB record is available. Source: "Microsoft SQL Server Native Client 10.0" Hresult: 0x80004005 Description: "Unable to complete login process due to delay in opening server connection". End Error Error: 2013-12-10 06:03:40.41 Code: 0xC00291EC
- User use Excel to connect to the Cube on my server. Often they got timeout errors. When they connect again it will work.
Are there any solutons on this?
Thanks a lot!
