Problems and solutions of computer name duplication in LAN

Two days ago, there was a problem with the computer of the company's colleagues. At that time to find me can not solve, and later after groping or resolved, very happy to share with you the joy and experience. So this lesson with you talk about the local area network computer name duplication resulting in shared printers can not be shared issues

Before we look at the problem, let's look at the simple architecture of our company.

(Network architecture diagram in case of problem)

In such a network architecture, what symptoms occur are:

If the same local area network computer name duplicates, will not be able to share printers and shared files;

For example, a colleague B computer accessing a printer server will not be able to link printers and access shared files;

Second, but strange, colleague B computer can remote desktop access to the printer server, but also normal ping the printer server;

Third, colleague B computer system will also be in the taskbar will be yellow hint (hint computer and LAN computer Duplicate, at that time I think the duplicate name should not be related to the printer), into the system Event Viewer can see. What I encountered was as follows:

=========================================

Event Type: Error
Event Source: Service Control Manager
Event Type: None
Event id:7000
Date: 2011-11-15
Event: 8:56:53
Users: N/A
Computer: J1
Describe:
The description of the event ID (7000) cannot be found in the resource (Service control Manager). The local computer may not have the necessary registration information or message DLL files to display messages from a remote computer. You may be able to use the/auxsource= identity to retrieve word descriptions, and to view Help and support for more information. The following information is part of the event: Ati HotKey poller,%%2.

=========================================

When the above problem occurs, I view errors and printer settings through events, and troubleshoot errors. Eventually can not solve, to the second day I want to reload the system, I try to try to modify the computer name, after the modification, the printer can link, restart will not have the wrong event, and finally succeeded!

Tisp:

How do I modify the computer name? Actually, it's very simple.

1. Right-click the computer (W7) or My Computer (XP) attribute, select the computer name.

2. Change the name of the computer, and then restart the computer after the modification is OK.

(in XP mode, click Change Modify)
