AX Installation problem

I was tried to install the ax(single installation) on the laptop which is running on the xp os . After installation i was not able to access the aos from client and prompting the message "Failed to establish connection". First verified the client config utilities there is truncation in the aos name. manually enter the name on the utility and also checked the registery where the ax information stored agai enter the correct name for aos. system is not up. Finally rename the hostname to with lessthan 10 character and tried to install the ax. it has been up and working fine.
