SET IIS APPLICATION ISOLATION LEVELS (LOW > IN PROCESS)

Low level: In low application protection, the spawned application (for example, a PERL script) will run in the same address space of the Web Services (Inetinfo.exe, that is, IIS itself), which is impersonated as the Anonymous user of the Web site. However, an *.exe application spawned from the script, runs in SYSTEM context and hence gets full control of the physical server. This is why low application protection is discouraged in shared hosting environment. 

1. Using the Explorer, browse to the C:\Program files (x86)\Mail Enable\BIN directory double-click the "MEInstaller.exe" utility.
2. Select "Set IIS application protection (Low > In process) to set the IIS application protection to low level (Not recommended for Mailenable).
3. Select the execute button and wait for the setting to be changed.
4. To check that the setting has been changed to "Low level".
    - Go to Control panel>Administrative Tools>Internet Information Services.
    - Expand the computer name in the tree in the left hand side window.
    - Expand "Default Web site".
    - Right-click MEWebmail, and check that the application protection is set to low.

SET IIS APPLICATION ISOLATION LEVELS (MEDIUM > POOLED)

Medium Level:  This is introduced in IIS 5.0. All spawned applications use the same "dllhost.exe" thus sharing address space amongst themselves, although separate from Inetinfo.exe. This is a balance between security and performance in a shared hosting environment and hence the most popular choice. Spawned processes (scripts) run in Anonymous user context. All executables spawned from scripts will run in IWAM_machinename context (same as High isolated).
 
1. Using the Explorer, browse to the C:\Program files (x86)\Mail Enable\BIN directory double-click the "MeInstaller.exe" utility.
2. Select "Set IIS application protection (Medium > Pooled)
3. Select the execute button and wait for the setting to be changed.
4. To check that the setting has been changed to "Medium Level".
    - Go to Control Panel>Administrative Tools>Internet Information Services.
    - Expand the computer name in the tree in the left hand side window.
    - Expand "Default Web Site".
    - Right-click MEWebmail, and check that the application protection is set to Medium.

SET IIS APPLICATION ISOLATION LEVELS (HIGH > ISOLATED)

High Isolated: In high application protection, each spawned application runs in a separated address space of dllhost.exe. One separate dllhost.exe process is dedicated to each Web site, which serves all the requests for that site. This achieves maximum security in a shared hosting environment, although this comes with a performance price. Spawned processes (scripts) run in Anonymous user context. All executables spawned from scripts will run in IWAM_machinename context.

1. Using the Explorer, browse to the C:\Program files (x86)\Mail Enable\BIN directory double-click the "MEInstaller.exe" utility.
2. Select "Set IIS application protection (High > Isolated).
3. Select the Execute button and wait for the setting to be changed.
4. To check that the setting has been changed to "High isolated".
    - Go to Control Panel>Administrative Tools>Internet Information Services.
    - Expand the computer name in the tree in the right hand side window.
    - Expand "Default Web Site".
    - Right-click MEWebmail, and check that the application protection is set to High Isolated.

NOTE: Recommended IIS application protection is "HIGH ISOLATED".
