Windows NT and 2000 often run into very
much the same application errors that the Windows 9x operating systems
have. For example, the application properties may be incorrect, the
Registry entrees might be missing or corrupt, or the .DLL files may be
corrupt. However, the Windows NT/2000 operating systems are usually
part of an integrated network, which means that a whole new host of
problems associated with the applications can occur. Users may not be
able to gain access to folders, permissions that are set on files or
folders may be too restrictive for the end user trying to access them,
or the permissions may not be restrictive enough. The end users then
may not be able to set any NTFS permissions on the files or folders
containing the files.
Windows 2000 Task Manager The processes tab provides information used to identify applications that might be slowing down the operations of the system. Sometimes when an application crashes it hangs the systems processor up as well, which will cause the rest of the system to lock up or slow down to a state that makes it unusable. The process tab tells the percentage of CPU usage that a particular application is using. If an application is not responding and it is "hogging" the CPU, shut down the application and see if the system returns to normal. The performance tab allows users to view a graphical interface showing the processor performance and memory usage. Past and current usage can be viewed to obtain information about the applications that were running and at what point they caused the system to lock up. |
Access the Task Manager by pressing the CTRL+ALT+DEL buttons
and then click the tab labeled Task Manager. The Task Manager
displays a list of active applications and helps to identify the
applications that are currently not responding. It can switch to a
particular application to troubleshoot it if there are problems with
it. Alternatively, choose to end the application, which will shut down
the application if it has crashed and is not responding.
