One morning to suddenly tips can not open the login "SDxxxN_SDACCSET" in the requested database, reinstall the database and the speed of the server files can not be resolved.

Suddenly I remembered that the day before I had tried to use the encryption function of XP's NTFS partition and permissions management to test encrypting the folders in the installation directory of SDACCSET, and then I used the same method to cancel the encryption, and finally I got it done, so if I have ever had to operate in such a way, I can try it.

Folder Properties - General - Advanced, Cancel "Encrypt content for data protection"

At the same time, we also need to set the permissions: Folder Properties - Security, see if the EVERYONE and ADMINISTRATOR owners have been added to the folder, and see if there are full permissions. permissions. If you don't have it, add it.

My problem in the Internet to find a half a dozen methods can not, and then is their own analysis is not the problem of this permission, because I deleted the authorization of the EVERYONE, resulting in the database may not be able to access the library file in the speed of the speed to the entire speed of the installation of the directory to add on the good.

I hope this helps.
