It's not, I don't think, a problem with outside access as I cannot access it from within either. From inside or out it used to be mail.xxx.com/exchange. Now from within it only works if I insert the exchange server's internal IP address/exchange. OWA (Exchange 5.5 on Win2K server) was working fine until I changed DSL lines. I have good e-mail in and out, but cannot access OWA from outside. I use simple SMC Barricade firewall with one IP address and 192....... addresses doled out within. I can access OWA properly from within if I use browser to inside IP address/exchange, but not by using mail.domain.com/exchange as I did before, inside and out. Is this some DNS setting I must make inside? I do not at this time run DNS inside. -----Original Message----- From: Rao [mailto:Hanumantharao@xxxxxxxxxx] Sent: Monday, June 23, 2003 4:46 AM To: [ExchangeList] http://www.MSExchange.org/ This is a multi-part message in MIME format.
