Issue: Slow StoreFront Web performance

Symptom

Windows-based thin clients would take a longer than expected time to connect to a Citrix StoreFront web store.

For security reasons, firewalls and/or proxies are preventing the clients to access the Internet.

Disable Internet Explorer's server certificate revocation:

Internet Options > Advanced (tab) > Security (section) > Check for server certificate revocation

[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\WinTrust\Trust Providers\Software Publishing\]
"State"=dword:00023e00

Decimal value: 146944

For older versions of Internet Explorer, the registry location is different:

[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\]

"CertificateRevocation"=dword:00000000
