When you run Risetup.exe, the BINL (Boot Information Negotiation Layer) service is installed.

The BINL service answers clients, validates and passes client information to/from the server. For performance or troubleshooting, you may wish to tweak the following values at HKEY_LOCAL_MACHINESystemCurrrentControlSetServicesBinlsvc, but you must first create the Binlsvc key using Regedt32:

Value Name

D e s c r i p t i o n

 Port 

 REG_DWORD 

 4011 

 The standard port that the PXE client uses. 

 LdapOptReferrals 

 REG_DWORD 

 0 

 If set to 1, BINL allows referrals when connecting to a nonglobal catalog. 

 ResponseDelay 

 REG_DWORD 

 0 

 The number of seconds to wait to respond to a client when BINL can't find an account, so other servers that may own the account can respond first. 

 LdapTimeout 

 REG_DWORD 

 30 

 The timeout in seconds for LDAP commands. A value of 0 is treated as .5 seconds. 

 CacheExpire 

 REG_DWORD 

 25000 

 The number of milliseconds that BINL waits until it expires DS cache entries. 

 CacheMaxCount 

 REG_DWORD 

 250 

 The maximun number of DS entries to cache. Once exceeded, performance will suffer. 

 DefaultServer 

 REG_SZ 

 The FQDN of the DS server. When DefaultServer is not present, the computer uses its' known server. 

 DefaultGCServer 

 REG_SZ 

 The FQDN of the DS global catalog. When not present, the computer uses its' known server.

 The number of seconds between complete re-reads of all the BINL parameters. 

 MaxDSErrorsToLog

 How many LDAP errors are logged within the DSErrorInterval. If exceeded, a generic summary error is logged. 

 DSErrorInterval 

 REG_DWORD 

 10 

 The number of minutes for the MaxDSErrorsToLog entry. 

 AssignNewClientsToServer 

 REG_DWORD 

 0 

 A value of 1 secifies that new clients should be assigned to a 'server', preventing other servers from responding.
