Hi,
you're probably in a situation similar to the following one:
In special cases, the consistency rules may be browser dependent. For instance, if the Web Server hostname has the short form mycompany.com and Lightstreamer Server hostname has the form push.mycompany.com, the "mycompany.com" domain has been found not to be accepted by Internet Explorer prior to version 8 (hence, no domain setting is available in this case, as "com" is too broad to be accepted). The limitation affects all cases in which the domain name is the same as the hostname.
so you should change the hostname of the web server to something like www.ClientCompanyName.co.ke

more details here: http://www.lightstreamer.com/docs/cl...html#setDomain

Let me know if this solution doesn't work.
