公司 AD,Windwos 2003 Server...欲汰換,IP:192.168.100.1
新AD2, Windows 2012 Server R2,IP:192.168.100.2

先行將 AD:192.168.100.1 斷線後,
將AD2上了AD所有功能後, 將IP改為 192.168.100.1
以避免之前的設備DNS指向192.168.100.1

完成後,其他電腦及設備,目前無大問題,皆能指向 AD2:192.168.100.1

唯有一台 XP電腦,但,應與XP無關,公司內多是XP系統的電腦,
就這台連不上:192.168.100.1 或 AD2主機....傷腦筋!!

處理過程:

1. Ping 192.168.100.1 request time out.

2. echo %logonserver% = AD (但,實際已斷線)

3. 將XP網域變更工作群組.

4. Ping 192.168.100.1 request time out.

5. Ping AD2 request timeout

6. nslookup ....解析不到 AD2 / config /flushdns N遍也沒用...

7. 也無法再將XP加入網域....找不到

8. 只好將 AD:192.168.100.1 重啟(還好OS還可以登入)

9. 再變更 AD IP:192.168.100.2

10. XP, ping 192.168.100.2 OK, 加入網域 OK.

11. 但, 可 ping 192.168.100.2
    可 ping AD 要等,但,仍可解析 192.168.100.2,找到後, 且,可Ping

12. 目前,重開機N遍,仍 Ping不到 192.168.100.1
    或 AD2 :Ping request could not find host AD2. Please check the name and try again.

13. XP DNS設定為 192.168.100.1

14. nslookup:
    DNS request timed out. time out was 2 seconds.
    Can't find server name for address 192.168.100.1:Time out
    *** Default servers are not available
    Default Server:Unknow.
    Address:192.168.100.1
    ad.domain.com
    DNS request time out
    timeout was 2 second.

    ad2
    Ping ad2.domain.com
    [192.168.100.1]with 32 bytes of data: Request timed out

15. 將 XP DNS設定為 192.168.100.2 (AD)

16. nslookup (一切正常)
    Default Server: ad.domain.com
    Address:192.168.100.2

    ad.domain.com
    Server:ad.domain.com
    Address:192.168.100.2
    Name:ad.domain.com
    Address:192.168.100.2
    ad2.domain.com
    Server:ad.domain.com
    Address:192.168.100.2
    Name:ad2.domain.com
    Address:192.168.100.1

    請教如何排解?? 感謝.
