用Windows server 2008 R2 DNS添加ISA WPAD的别名老是解析失败,并且在DNS event view中看到有这样的错误:

Updating the block list

    dnscmd /info /enableglobalqueryblocklist
  2. To display the host names in the current block list, type the following:
    dnscmd /info /globalqueryblocklist
  3. To disable the block list and ensure that the DNS Server service does not ignore queries for names in the block list, type the following:
    dnscmd /config /enableglobalqueryblocklist 0
  4. To enable the block list and ensure that the DNS Server service ignores queries for names in the block list, type the following:
    dnscmd /config /enableglobalqueryblocklist 1
  5. To remove all names from the block list, type the following:
    dnscmd /config /globalqueryblocklist
  6. To replace the current block list with a list of the names that you specify, type the following:
    dnscmd /config /globalqueryblocklist name [name]…
