IIS: SSL Certificate Disappearing after import

After import the certificate into IIS, when I navigated away from the Server Certificates window, the certificate would disappear.
I could see the certificate in the server’s Personal Certificate Store using MMC (Microsoft Management Console) but it wouldn’t show up in IIS.

After investigate, I found below solution for this issue:

Save the three portions of the certificate into three separate files (Note: The Intermediate Certificate is optional, if you were not supplied with one, just skip the steps involving it):

privatekey.txt – Copy and paste the contents of the private key including the begin and end lines.
certificate.txt – Copy and paste the contents of the Regular Certificate including the begin and end lines.
intermediate.txt – Copy and paste the contents of the Intermediate Certificate including the begin and end lines.

Upload all these files to a linux server, and run

openssl pkcs12 -export -out certificate.pfx -inkey privatekey.txt -in certificate.txt -certfile intermediate.txt

then import the certificate.pfx into IIS

Citrix aplication failed to start (progress bar disappearred)

Iff the Citrix server is behind a RODC, and there is a slow wan connection between user’s computer and RODC. Sometimes, the Citrix application can’t start:

    The session initially begins to connect as normal. After the loading dialog box disappears, the explorer application fails to appear.
    If the session is viewed in the Delivery Services console while the application is loading, it first shows as connecting, and later shows as disconnected until finally the session disappears.

Use the following registry key that allows you to configure the time-out as follows:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlCitrixwfshellTWI
Name: ApplicationLaunchWaitTimeoutMS
Type: REG_DWORD
Data: 99990 in dec
Note: Specifying a value of less than 10000 reverts to 10000 because 10 seconds is the minimum override.
