View Desktop logon credentials screen takes 60 seconds to appear

When the Internet connectivity in your View desktop is disabled from a client using SSL, you experience these symptoms:
There is a delay of 60 seconds before you see the login credentials screen for the View desktop.
The login credentials screen may not appear and times out.
You may see a message stating that the certificate is invalid.
The View Client conducts a certificate revocation check when using SSL certificates. If the Internet connectivity is disabled, the client cannot complete this check and results in a 60 second delay before the logon screen is displayed.
To resolve this issue, reduce the timeout period for the certificate revocation check.
To reduce the certificate revocation check timeout:

• In the client machine, click Start, type regedit, and click OK. The Registry Editor window opens.
• Navigate to HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Cryptography > OID > EncodingType 0 > CertDllCreateCertificateChainEngine > Config.
• Click Edit > New > DWORD Value.
• In the Name field, type ChainUrlRetrievalTimeoutMilliseconds.
• Right-click the entry and click Modify.
• Under Base, select Decimal.
• Under Value data, enter 15000.
• Click Edit > New > DWORD Value.
• In the Name field, type ChainRevAccumulativeUrlRetrievalTimeoutMilliseconds.
• Right-click this entry and click Modify
• Under Base, select Decimal.
• Under Value data, enter 20000.
• Close the Registry Editor.
• Restart the client machine.

Use the View Client to connect to the desktop.

# Log in to Windows as the user whose shell you want to change.
