I'm a little confused
Of course you are. This thread is so full of assumptions that it's no wonder you're confused. I think that's partly because your initial question was not very precise and mixed up different topics. So, the best way to address your issue is to try figuring out what exactly it is you want to achieve.
So: in your initial post you write

they must type the whole name like this "

This seems to ask multiple questions actually. First you want to access "myserver" as "isdwiki". Second you want to redirect from "/" to "/dokuwiki/doku.php?id=start".
First of all "isdwiki" is not a full qualified domain name, so this would not be resolvable on the Internet - however "myserver" isn't either. If you are on your own network, you can make your local DNS resolve a simple hostname. This however requires access to the local DNS server. I don't know if you do have that. OTOH "isdwiki" is not much shorter than "myserver" so I don't even know if that's worth the trouble.
Now of course it might be possible that "myserver" and "isdwiki" are not the actual names you're talking about and you just used them as placeholders for some longer, full-qualified names? I guess you should tell us then.
Next up is the path part of the address "/dokuwiki/". You could create a redirect to redirect "/" to "/dokuwiki" either through a .htaccess (assuming you're running Apache) or through a direct setting in the web server's config. However if you can do that, it means there is nothing else running on the same server at "/". So why not move all of DokuWiki one directory up? Get rid of the "dokuwiki" folder and install it directly in the server root.
Of course there might be something running at "/" - so you can not redirect from there. In that case you may want to have your own virtual server configuration which points directly to the wiki. This again plays together with the DNS setup above.
Finally there is the "doku.php?id=start" part. As atiq4pk said in the very first reply, that's something DokuWiki's rewrite option can help you with. It would turn "doku.php?id=start" into just "start". But that seems to be the very last step of what you want to achieve.
All the replies you got so far where well intentioned but all assumed something from nothing and thus weren't really helpful at all.
I totally realize that the same goes for my reply. It will probably not help you much right away but hopefully gives you some pointers what you need to Google/ask your Admin/specify in your next post.
