I had the MAX 4000 working fine for dialup with an NT4 Server as a Radius server. The ONLY changes made were the installation of Service Pack 6 and a deleted DHCP scope that was added back later. I am at a loss here- everyone who logs in gets an invalid username or password error. Does anyone know of any issues with SP6? ________________________________ Jeffrey Zacher, MCSE Network Administrator Wisconsin Education Association Council PHONE: 608.298.2370 FAX: 608.276.8203 CELL: 608.235.1262 E-MAIL: Zacherj at weac.org WEB: www.weac.org
