Error Code 17750

Question

Could not load the DLL xpstar.dll, or one of the DLLs it references. Reason: 5(Access is denied.)

Answer 1

Hi @Shweta Mane ,

As soon as we know the DLLs was missing, we don’t know how many such more DLLs might be missing. Based on my search on the internet it comes from Visual Studio Shell (vc_red.msi). I asked them to install VS Shell from SQL media and meantime, copy that missing file from a working machine. As soon as file was copied, we were able to connect SQL using SQLCMD and then we start SQL server normally.
For more details , please see:

Answer 2

"Access is denied" can be due to lack of permissions (for the SQL Server service account), but it can also mean that the file is use by another process.

As Olaf says, you need to share more information. In which context do you get this error? What is the output of "SELECT @@version"?
