Wrong network map cache credential record causes backup scheduled task to fail

Technology is to share, today for everyone with a production environment in the wrong article, I hope that everyone in the work after the wrong reference. Do not say directly on the dry:

Problem Description :

Customer set n Scheduled tasks to periodically back up the corresponding database and related log files and other information, after the domain policy expires after changing the domain account password information, after each server-side update credential verification, all server scheduled tasks are performed normally, except in 2003 the backup plan on this server has failed, Customer related service People study n long time and temporarily through the manual backup to do a good job of backup and to us to resolve the incident.

The relevant error information is as follows:

\\server\c$ is not accessible. You might not has permission to use the This network resource. Contact the administrator of the "this" to "find" If you have access permissions.

Multiple connections to a server or shared resource by the same user, using more than one user name, is not allowed. Disconnect all previous connections to the server or shared resource and try again.

Problem Analysis :

See if URL access is normal (\\10.0.0.1\d$ access is normal, access \\10.0.0.1\c$ access failed, separate access \\10.0.0.1 prompt to enter account information, input after the pop-up window error) (All other servers and client access to C $, d$ no problem):

Steps to resolve:

1. Check the share permissions, sharing policy (other client or server can access the information under C $, except 2003 on the servers), and confirm that there are no separate restrictions on the policy;

2. Through net share to see if C $ is shared, execute net use */del Delete network map cache information;

3. Customer problem solving.

Attached net use annotations:

NET use S: \\IP Password/user:administrator establishes a network mapping of corresponding disk characters;

NET use to view network mapping information

NET use s:/del delete the network map corresponding to the S-disk

NET use */del Delete all credential records

Using the net USE command to create a network image,

Example: net use \\10.0.0.101\d$ password/user:administrator

If you want to create a network image driver, you can add the specified drive letter after net use

NET use Z: \\10.0.0.101\d$ password/user:administrator

I am not a school born, but also not Daniel, but the technical aspects of a little insight, another reason is because my memory is not too good, haha, do a document collation for everyone to refer to the study, hope that everyone less detours, common learning common progress.

In addition, the wrong or the meaning of the blog is to promote better learning and thinking about technical issues, do not rely on these content psychology, production or actual circumstances suggest that we do more summing up, good at thinking about the problem, at the same time to have a humble shared psychology to serve more of the later. Technology is the dream, knowledge is shared.
