The best way to resolve this is to purchase a trusted CA signed SSL server certificate and install it on your View Servers. This way your users will have the assurance that they are connecting to a verified View environment.
The main purpose of SSL between the View clients and a View environment is to prevent attacks of eavesdropping and tampering of this communication.
As with any secure web-site, if you stick with an untrusted CA or self-signed SSL server certificate, your environment is vulnerable to a man-in-the-middle (MITM) attack.
The default for View clients is to show a warning message if an untrusted certificate is used. You will also eliminate this warning when you install a correct certificate.
For instruction on this look at the Configuring SSL Certificates for View Servers in the View Installation Guide and also the Obtaining SSL Certificates for VMware View Servers guide.
The alternative is to ignore the warnings, but then your View environment will remain vulnerable.
Hope this helps.
