set rs=server.createobject("adodb.recordset")
rs.open sql,conn,1,1
if not rs.eof then
rs.close
conn.close

1.好像没什么错误 你把第一句
username=request.form("username")
password=request.form("password")
replace去替换什么呢？
2.response.Write"<script>alert('对不起，用户名或密码错误');location=""login.asp"";</Script>"
3.sql="select * from admin where(username='"&username&"' and password='"&password&"')" 看一下你在 WHERE 后 那个 username='"&username&"'前面的username 和你页面INPUT名字一样吗？平常都是写admin 你看看是不是有问题
<%
username=replace(request.form("username"),"'","''")
password=replace(request.form("password"),"'","''")
sql="select * from admin where(username='"&username&"' and password='"&password&"')"
set rs=server.createobject("adodb.recordset")
rs.open sql,conn,1,1
if not rs.eof then
