There are many root causes for this issue.
1. It could be network related issues - Speed/congession/Duplex settings.
2. It could be your server performance - Hardware/OS/Exchange.
3. It could be the client side issue.

Check Event Logs on the server. If nothing specific, enable necessary diagnostic logging on Exchange and keep monitoring the event logs.

Is it happening for the whole day or only at certain duration?

NOTE: To get quick response and resolution, always provide clear details of the issue.

Also check the RPC dialogue box on the client end for the server name.
Is it showing your DC name or Exchange server Name?

It is like my two domain controllers are crashing

I get this errors in the event log > application log:

LDAP Bind was unsuccessful on directory dc.offices.netmedia.hr for distinguished name ''. Directory returned error:[0x51] Server Down.  

Process INETINFO.EXE (PID=424). Topology Discovery failed, error 0xffffffff.

Process MAD.EXE (PID=3724). All Global Catalog Servers in use are not responding:  
primari domain controller
sec domain controller

Background thread FDoBuildCatalog halted on database "First Storage Group\Mailbox Store (EXCHANGE)" due to error code 0x80004005.

No, Hopefully It is not DC issue. To make sure check the health of your DCs through Event Viewer.

It should be your network issue. We faced the same issue for 6 months. Actually our SMTP connectors go down frequently. Then randomly we used to get the same event what you mentioned here. Finally we traced it to be a network (LAN) issue.

Check your cables running between switches to DCs and Exchange servers. If it is connected to a Layer 3/ layer 2 switch, try to change the switch port.

Here are the errors on the primary domain controller:

Event Type:      Error
Event Source:      DNS
Event Category:      None
Event ID:      6525
Date:            13.12.2007
Time:            8:35:08
User:            N/A
Computer:      DC
Description:
A zone transfer request for the secondary zone colocation.mplus.net was refused by the master DNS server at 192.168.254.100. Check the zone at the master server 192.168.254.100 to verify that zone transfer is enabled to this server.  To do so, use the DNS console, and select master server 192.168.254.100 as the applicable server, then in secondary zone colocation.mplus.net Properties, view the settings on the Zone Transfers tab.  Based on the settings you choose, make any configuration adjustments there (or possibly in the Name Servers tab) so that a zone transfer can be made to this server.

Check this:
============================================================================
To verify that the primary DNS server is configured to allow zone transfers from the secondary DNS server
 1.  On the primary DNS server, click Start, point to All Programs, click Administrative Tools, and then click DNS.
2.  In the console tree, double-click the DNS server.
3.  In the console tree, double-click Forward Lookup Zones or Reverse Lookup Zones, as applicable.
4.  Right-click the zone, click Properties, and then click the Zone Transfers tab.
5.  Ensure that the Allow zone transfers check box is selected.

If zone transfer fails with Event ID 6525 Zone transfer for secondary zone <zone_name> refused by master server and the master server allows dynamic updates for the zone, these failures are due to the zone transfer throttling mechanism, and they are expected. This mechanism limits the number of zone transfers to allow regular dynamic updates to take place.
