Recently (in the last few days), my installation of IE8 has been taking 15 to 20 seconds to load my home page. Specifically, the sequence of events (as reported by WireShark) is:-
- Browser issues a
DNS Aquery to resolve the home page server's IP address.
- Browser then spends the next 15-20 seconds broadcasting
DNS SRV _LDAP._TCPqueries, (roughly on a 2 second tick) to which it receives no answer (we have no LDAP servers).
- Browser re-issues the
DNS Aquery and resolves the server's IP address again.
- Finally, the browser issues an
HTTP GETfor the home page.
Does anyone know why this is happening?
- Possibly related to this question
@Massimo, LDAP query is :-
Domain Name System (query) Transaction ID: 0x11c5 Flags: 0x0100 (Standard query) Questions: 1 Answer RRS: 0 Authority RRS: 0 Additional RRS: 0 Queries _LDAP._TCP: type SRV, class IN Name: _LDAP._TCP Type: SRV (Service location) Class: IN (0x0001)
