By filling up allrepparttar free space, impurities are effectively prevented from entering and damagingrepparttar 133383 bearings andrepparttar 133384 lubricating intervals can be extended.

For most other greases,repparttar 133385 general rule applies.

Bearings can be divided into two categories - non-separable and separable bearings. No matter which bearing type it is,repparttar 133386 general practice is to fill uprepparttar 133387 space between inner race,repparttar 133388 outer race, andrepparttar 133389 rolling components (ball or roller) on both sides ofrepparttar 133390 bearing. Because of its consistency,repparttar 133391 grease should be able to remain in place without dropping off. In this way, we can ensure thatrepparttar 133392 rubbing contact surface actually has grease on it.

For relubrication, how much is enough? The following formula gives a good indication:

G = 0.005 DB

where, G = grease quantity in grams D = bearing outside diameter in mm B = total bearing width in mm

By practicing proper lubrication,repparttar 133393 bearings should be able to last for a long time. However, bearings can still fail if it has not been installed properly or for other reasons.

Until next time...

But, what happens if you have multiple application pools running asrepparttar same user? For example, if you keep torepparttar 133382 default NETWORK SERVICE user but create multiple Application Pools, you may want to know which process belongs to which App Pool. Component Services doesn't work for this anymore.

Enough already, tell me how to do it!

Have no worries, Microsoft has given usrepparttar 133383 exact tool forrepparttar 133384 situation. IISApp.vbs lists allrepparttar 133385 applications, their PID and their App Pool name.

The script is already placed in systemrootsystem32 on Windows Server 2003 so simply go to your Command Prompt and type in iisapp.vbs (the .vbs is optional) and you'll have an instant list of allrepparttar 133386 App Pool information you've always wanted to know. You may need to type cscript iisapp.vbs if CScript isn't your default WSH script host.

Let's see an example ofrepparttar 133387 output:

W3WP.exe PID: 1468 AppPoolId: AppPoolForSite1.com W3WP.exe PID: 3056 AppPoolId: AppPoolForSite2.com W3WP.exe PID: 1316 AppPoolId: AppPoolForSite3.com

Direct fromrepparttar 133388 horse's mouth, Microsoft documents this:

Summary

We've seen here that using iisapp.vbs, you can painlessly match uprepparttar 133389 PID torepparttar 133390 friendly name ofrepparttar 133391 Application Pool.
