用OUTLOOK收發信正常可是卻無法進入WEBMAIL

[ijen]

我是初學者,我在自己電腦裝了個人版,目前發現一個問題就是當我從公司以OUTLOOK連回自己的MAIL SERVER收發信時都正常,卻無法連上WEBMAIL跟遠端控制台,我WEBMAIL 跟遠端控制都有啟動,而且也確定81&7777PORT並沒有被防火牆鎖住,我在家用另一台NB以ADSL連上網後在進入WEBMAIL卻又可以.....
請問問題會是出在公司網路限制ㄇ?
另外我試著了解MX,以下是我查到的資料能否告訴我是否正確呢?
C:\>nslookup

公司不能用的話, 可能是公司有限制吧? 用 80 PORT 試試吧~~
