Windows Server Standard is an operating system that has been developed for small as well as medium sized businesses. Windows has come up in many versions and edition and the one we are reviewing today if Windows Server Standard. It is an edition which supports file dowhload printer sharing plus it downoad offers very secure Internet connectivity. You can also download Страница 7 Professional. The registry performance has also been enhanced and it also includes SMP locking performance.

It has also got an Internet Connection Firewall which provides Internet security in the form of a firewall. ICF provides protection on computers which are directly connected to Internet. It also supports. NET Framework which will enable the developers for creating Web applications. The security and stability has been enhanced greatly in Windows Server Standard.

Run PoolMon. Go to the PoolMon directory. Starting PoolMon changes the data, so you must let it run until it reaches a steady state and the data is reliable. Stop PoolMon, wait for 30 minutes, and then restart PoolMon. You can map driver files for tags directly in poolmon. To do this, make sure the pooltag. You can copy pooltag. Run the poolmon as follows:. So we have got the list of driver files that may cause the problem.

Now you have to identify what drivers and system components these files refer to by their names. To do it, you can use the sigcheck tool from Sysinternals. If a memory leak resulted in a BSOD, you can identify the problematic driver in a memory dump file. If the automatic driver update is enabled in Windows, check to see if problems started after installing new drivers.

Try to roll back to the previous driver version and see if the problem persists. If the problem is solved, disable automatic driver update. In some cases, the installed Hyper-V role is causing a memory leak to the non-paged pool. This is mainly useful when the tag is comprised of three letters.

The way to search multiple directories, using the command shown by Microsoft KB Q How to find pool tags that are used by third-party drivers , is to use:. In that example, TagT represents the tag text to search for.

If that example doesn't work, change the part after the word cd to use another one of the recommended directories to search in. A method using a graphical interface may also be available. Using the graphical interface, one probably? This software probably isn't the first choice for many users, because it may not be pre-installed.

If the offending software appears to be svchost. If that seems to be what is using up memory, check for high amount of used Handles. It may also make sense to check for software using a very large amount of threads. Perhaps seventy thousand 70, might be a reasonable threshhold to determine if software is using too many handles.

Normally processes use many less handles than that digits , although an offending program may use many, many more than that possibly millions? Now that? If paged pool memory is low and the related pool tag is MmSt, the Memory Manager may be causing the issue because of a large number of files being opened.

Put a different way, this is the pool tag that is used to map the OS memory used to track shared files. See if there are updates to the software. BackupExec seemed to cause this as well. If there isn't an update to address the problem, the most ideal situation would be that an update becomes available to address the problem. One option on how to proceed may be to contact the software vendor and see if it is possible to work with a software developer to resolve the issue.

This may take more time for an end user than some other resolutions, but it may also help other users of the software, so this option may be altruistically preferred. See the section about providing information to a developer. If one occurs, find out why, and if it is necessary.

If it is not, perhaps just remove that switch. Another option involves restarting that software which can be done by restarting the entire server. Upgrading to a bit operating system perhaps as part of a process of replacing a bit CPU with a bit CPU may make the problem become insignificant.

Software that is using up too much NPP may still have the problem that memory is not being handled correctly, but the impact may become negligible. Another way to respond may be to move the software to another machine. Moving the software to another machine may fix the issue. More likely, doing so will simply move the problem to another computer. However, that may be preferable so that the problems don't keep affecting a computer that also performs other important functions.

This may or may not be feasible depending on what the software is. There may be some advantages to running software on a specific machine. Another option may be to replace the software with a competing software solution , or if the software is no longer needed, to just stop using the current software.

Consider moving user mailboxes to another server to reduce server load and see if the problem stops. See the section about Troubleshooting memory leaks in Microsoft Windows. Here is some other documentation that may help some developers: PREfast looks to be a development tool to catch issues that compilers may not catch. Overview There are two certain types of memory that is considered to be used by the kernel, and which could run out.

Here is how that number was determined as a general number: Looking at machines using bit Windows Server or bit WinXP Note that not all machines will be able to function right if million bytes are used. Considering bit machines and those using newer versions of Windows A sensible starting point for an alerting threshold may be to match the starting alerting threshold that is used for bit operating systems. Debugging software Then add the values?

Debugging Tools KB shows that using! Additionally, this switch may increase the risk of running out of pool memory. Turning off TCP Chimney? Get details while they are available Generally, it is best to try to gather information before rebooting the server.

Here are some of the details that can really help, so start storing these details into files which may be reviewed later if needed : Programs using large amounts of Non- Paged Pool Memory Determine what programs are using up large amount of pool memory. If not, select V iew, S elect Columns User mode dump heap Umdh This information has not been heavily tested by this guide, but is being provided for reference.

This may be less likely to be useful, but in case the information may be useful, record the information now since the information may not be so easily available later. To do so, run: TaskList. One way to get this information is to use Poolmon. Identifying which memory tags are using up Non-Paged Pool Memory by using Poolmon Poolmon may be a great resource if it is available, as it will not only show the memory use but also the memory tags. Be sure to get the Native x64 release if that is what is desired.

However, note that version 6. A text file of output may be searched without the screen updating regularly. To show only non-paged pool memory, either use: poolmon -b -n poolsnap. What's this? One of the potentially most useful parts of Poolmon is to show the Pool Tags being used. Warning about another problem The severe problems on bit machines that are lacking NPP are often seen most frequently on servers that get rebooted less than once a month. Identifying the software The basic process is to start by identifying what software is using up too much memory.

Getting the used pool tags This is discussed elsewhere, in the section about Finding that Pool Tags are used. Finding out which software uses a pool tag The basic process may be to find out what file, or driver, uses a Pool Tag.
