For whomever is intrested, I will post what I found about this: Using the ISA SDK I could determine in what mode the ISA is installed. However, if you want to use the registry, you will first have to look up this value: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Fpc\CurrentArrayGUID (REG_SZ) Using that value, you have to open the following key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Fpc\Arrays\{VALUE OF CurrentArrayGUID}\msFPCComponents (REG_DWORD) This field has a DWORD which is constructed from the following values using the bitwise OR operator: fpcNoComponents =0, fpcPacketFiltering =1, fpcNAT =2, fpcWebProxy =4, fpcHTTPTransparent =8, fpcGenericFwProtocols =16, fpcFirewallExtensions =32, fpcAllComponents =255 Using this, one could determine what mode ISA is installed. Other nice values in here are: msFpcCreatedTime (hold the date when ISA was installed) msFpcDescrition (has a description of this ISA installation) Jeremy. -----Original Message----- From: Jeremy Pullicino Sent: Friday, July 20, 2001 12:23 PM To: 'isalist@xxxxxxxxxxxxx' Subject: Determine if ISA server is installed as Firewall mode only. Dear ISA server.org, Does any ISA guru know if there is a way to determine if ISA server is installed in firewall mode only or firewall/caching mode? Are there different services installed or some special regitry keys I could check?
