Mup.sys is a filesystem with an important role in computer networks. However, errors in this crucial can prevent a computer start correctly, or booting at all.
WHAT IS Mup.sys DO ON MY PC?
Mup.sys is used only by systems Operating latest range of Windows – Windows XP, Windows NT, Windows 2000 and Windows Vista. The file is involved in a component of the operating system called a Multiple UNC Provider (MUP). It is part of a software system that helps networking of computers to transmit files with each other to share a common language used to describe the locations of resources used by the network, such as shared files and devices. This is not as complicated as it sounds. For the user, this means that the locations of resources stored on a computer are described in the same way for each resource.
For example, when you look inside your hard drive and click on a folder, the folder location on your hard disk appears in the address bar. If you click on a folder or file, the location of the file may appear as something like C: \ foldername \ Filename. This structure is used for each file and folder on a computer, as well as peripheral resources such as scanners and printers.
What does this mean in terms of how the Multiple UNC Provider system works? When a program on a computer network attempts to access a shared resource, it uses a UNC path (the path refers to the location of the resource). The access request is sent to the supplier Multiple UNC, which then redirects the request that the computer on the network he is making.
The Multiple UNC Provider, therefore, is part of a networked system that allows computers to communicate them in a uniform manner.
So why Mup.sys CAUSE AN ERROR?
Mup.sys errors are usually caused by file corruption or a bug in the Windows operating system on the Mup.sys file. These errors Mup.sys May not load properly on your computer. The problem with this is that Windows tries to load Mup.sys whenever you start your computer if your computer is part of a network or not.
Therefore, if the file is corrupted to the extent that it can not be fully charged, your computer does crash or start rebooting every time it tries to load the Mup.sys file. In most cases, this happens even when the computer is started in Safe Mode.
WHAT Other errors may Mup.sys QUESTION?
Apart from the errors of file corruption as described above, Mup.sys May occasionally cause other types of errors, depending on your operating system and configuration.
A Mup.sys obsolete or damaged files may cause a variety of errors of non-network specific, most often in Windows 2000 and Windows NT. These may include errors in the wiring system files distributed between DCs and client computers, as well as more general network errors in networks running any XP, 2000, NT or Vista version of Windows.
In most cases, the root cause of these errors, including most of the following, lies in the use of an operating system that is not completely up-to-date.
Stop 0×50 Error (Windows NT 4.0)
This error occurs if your sound system is set to "No Sounds". The system can not handle this setting correctly – it looks for a file called "close.wav" on the network when the machine stop, even if the sound was turned off and the file will not be used. When this happens, a bug in the Mup.sys file causes the error message. This may occur when closing the computer.
STOP: 0×0000000A Error (Windows NT 4.0 Terminal Server Edition Service Pack 6a)
This error can occur at any time. The error is independent of system configuration or what applications are running. However, only computers running the above version of Windows NT are affected by this error.
Event ID 2012 (Windows NT 4.0 with Service Pack 3)
An outdated file Mup.sys may sometimes be the cause of Event ID 2012 Error in network computers running this version of Windows NT. This error may occur when you run an application that uses Btrieve engine version 6.15 (Btrieve is a database that uses a method of storing data that provides recovery time faster).
Not admissible Network (Windows 2000 SP1 or 2)
An error in Mup.sys May occasionally cause computers through a network to become non-responsive when a networked computer disconnects from the Distributed File System.
System Error 53 (Windows 2000, Windows NT 4.0)
This error can occur when you use a version of both operating systems who has not been day. The error due to an incompatibility between Mup.sys and distributed file system occurs.
