Hi, Could someone suggest me how to resolve the following issue on the ISA Server, ISA Proxy service terminates once every week, giving out an error message on the event viewer saying "proxy service terminated unexpectedly" I also see some errors pertaining to caching, a few minutes before this termination. The current cache size is 512 Mb. Service Pack 2 has been installed. Also, the ISA server is working only on caching mode and not as Firewall. Are there some settings I need to change in the caching properties to overcome this issue Request you to please respond with your valuable suggestions Regards Arun This e-mail and any attachment is for authorised use by the intended recipient(s) only.
